1. A tamper-evident container, comprising: a base tray having a bottom and a sidewall forming an interior volume, the base tray further comprising an edge extending peripherally outward from an upper edge of the sidewall; anda lid having an edge extending peripherally outward therefrom, the lid edge being configured to mate with the tray edge to close the container, the lid edge having an inner portion and an outer portion, the inner and outer portions having a perforated section therebetween, the perforated section extending continuously around the entire periphery of the lid such that no portion of the lid can be separated from the tray without separating at least a part of the outer portion from the inner portion along the perforated section, whereby the outer portion forms a tamper-evident seal removable from the inner portion for removing the lid from the tray,wherein the peripherally extending edge of the tray is disposed beneath the outer portion of the lid edge and extends peripherally outward to or beyond a free end of the outer portion of the lid edge to protect the tamper-evident seal. 2. A tamper-evident container formed by thermoforming, the container comprising, a base tray having a bottom and a sidewall forming an interior volume, the base tray further comprising an edge extending peripherally outward from an upper edge of the sidewall; anda lid having an edge extending peripherally outward therefrom, the lid edge being configured to mate with the tray edge to close the container, the lid edge having an inner portion and an outer portion, the inner and outer portions having a perforated section therebetween, the perforated section extending continuously around the entire periphery of the lid such that no portion of the lid can be separated from the tray without separating at least a part of the outer portion from the inner portion along the perforated section, whereby the outer portion forms a tamper-evident seal removable from the inner portion for removing the lid from the tray,wherein before the outer portion of the lid edge is removed, the lid edge is matable with the tray edge to secure the lid to the tray without applying heat or adhesive. 3. The tamper-evident container of claim 1, wherein after the outer portion of the lid edge is removed, the inner portion of the lid edge is configured for a snap fit with the peripherally extending edge of the tray for removably securing the lid to the tray. 4. The tamper-evident container of claim 1, wherein the inner portion of the lid edge comprises a tab having an edge that is exposed when the tamper-evident seal is removed. 5. The tamper-evident container of claim 1, wherein the lid is formed by a thermoforming process. 6. The tamper-evident container of claim 1, wherein the base tray is formed by a thermoforming process. 7. The tamper-evident container of claim 1, wherein the lid is formed of any of the following plastic materials: high density polyethylene (HDPE), polyethylene terephthalate (PET), polypropylene (PP), polystyrene (PS), and polylactic acid (PLA). 8. The tamper-evident container of claim 1, wherein the peripherally extending edge of the tray and the peripherally extending edge of the lid each has a corresponding peripheral channel configured so that one of said peripheral channels is received in the other of said peripheral channels for securing the lid to the tray. 9. The tamper-evident container of claim 8, wherein each of said peripheral channels comprises an inner wall and an outer wall joined by a channel wall, each of said channel walls being oriented substantially parallel to a peripheral plane of the tray edge and the lid edge. 10. The tamper-evident container of claim 9, wherein the perforated section of the lid edge is formed in the channel wall of the lid edge. 11. The tamper-evident container of claim 9, wherein the inner walls of said peripheral channels each forms an acute angle with its corresponding channel wall to create a snap fit between said peripheral channels when the lid is secured to the tray. 12. The tamper-evident container of claim 9, wherein the inner and outer walls of said peripheral channels each forms an acute angle with its corresponding channel wall to create a snap fit between said peripheral channels when the lid is secured to the tray. 13. The tamper-evident container of claim 12, wherein the inner walls of the peripheral channels each forms a smaller acute angle with its corresponding channel wall than the acute angle formed between each outer wall and its corresponding channel wall. 14. The tamper-evident container of claim 1, wherein the outer portion of the lid edge is in contact with the peripherally extending edge of the tray around the entire periphery of the tray. 15. The tamper-evident container of claim 2, wherein after the outer portion of the lid edge is removed, the inner portion of the lid edge is configured for a snap fit with the peripherally extending edge of the tray for removably securing the lid to the tray. 16. The tamper-evident container of claim 2, wherein the peripherally extending edge of the tray and the peripherally extending edge of the lid each has a corresponding peripheral channel configured so that one of said peripheral channels is received in the other of said peripheral channels for securing the lid to the tray. 17. The tamper-evident container of claim 16, wherein each of said peripheral channels comprises an inner wall and an outer wall joined by a channel wall, each of said channel walls being oriented substantially parallel to a peripheral plane of the tray edge and the lid edge. 18. The tamper-evident container of claim 17, wherein the perforated section of the lid edge is formed in the channel wall of the lid edge. 19. The tamper-evident container of claim 17, wherein the inner walls of said peripheral channels each forms an acute angle with its corresponding channel wall to create a snap fit between said peripheral channels when the lid is secured to the tray. 20. The tamper-evident container of claim 17, wherein the inner and outer walls of said peripheral channels each forms an acute angle with its corresponding channel wall to create a snap fit between said peripheral channels when the lid is secured to the tray. 21. The tamper-evident container of claim 20, wherein the inner walls of the peripheral channels each forms a smaller acute angle with its corresponding channel wall than the acute angle formed between each outer wall and its corresponding channel wall.
