1. A boil-in-bag pouch containing a foodstuff, wherein said pouch is in the form of an enclosed body having a front face, a back face, a top end, a bottom end, and first and second sides extending between said top and bottom ends, said pouch comprising: a) a single sheet of flexible sheet material having first and second opposed edges, wherein said sheet is folded along said first side and said second side to define said front and back faces, wherein opposed edges of said sheet are bonded by a longitudinal seal extending from said top end to said bottom end of said pouch;b) one or more diagonal lines of bonding are between layers of the sheet material and the diagonal lines of bonding extend obliquely from an intermediate region of the top and/or bottom of the pouch to an edge of the pouch, the said diagonal lines of bonding define two corners, respectively adjoining the top and bottom of said only one side edge of the pouch, from which the contents of the pouch are substantially excluded;(c) each of said top and bottom ends comprising a first transverse seal between said front and back sheets extending substantially completely across said end; and a second transverse seal between said front and back sheets spaced inwardly from said first transverse seal and extending substantially parallel to said first seal from said first side to an intermediate position, where it joins to said diagonal lines of bonding but does not extend further parallel to said first transverse seal beyond said intermediate position,d) a pleat extending from the bottom second transverse seal to the top second transverse seal along only one side of said body wherein the pleat comprises a first strip of the sheet material folded inwardly towards the front face of the pouch along said only one side of the pouch and a second strip of the material folded inwardly towards the back face of the pouch along said only one side of the pouch, said first and second strips meeting along a fold line located internally of said front and back faces, and respective top and bottom ends of said first and second strips being bonded in face to face relationship with said front and back faces, respectively, at said top and bottom transverse seals, and wherein said diagonal lines of bonding are formed between the first strip and the front face of the pouch and between the second strip and the back face of the pouch adjacent to each of said first and second ends, but said diagonal lines of bonding are not formed between the first and second strips. 2. The boil-in-bag pouch according to claim 1, wherein one or more tear starts are in the top and/or bottom end of the pouch, said tear starts being located proximate to said first side of the pouch opposite the pleated side. 3. The boil-in-bag pouch according to claim 1, wherein one or more lines of weakness extend substantially from the top end to the bottom end of the pouch, said lines of weakness being located proximate to said first side of the pouch opposite the pleated side. 4. The boil-in-bag pouch according to claim 1, wherein a handle is attached to the pouch body for suspending said pouch with the said second side lowermost. 5. The boil-in-bag pouch according to claim 4, wherein said handle is formed by a strip of sheet material extending between the top and bottom transverse seals and bonded to the pouch body at the top and bottom transverse seals. 6. The boil-in-bag pouch according to claim 5, wherein said longitudinal seal between opposed edges of said sheet material is a lap seal whereby a longitudinal flap of said sheet material extends on the outside of the pouch body from the top to the bottom of said body and bonded to said front and back faces at said top and bottom transverse seals, and a longitudinal cut extends along at least a portion of said flap whereby said handle is formed by a distal portion of said flap. 7. The boil-in-bag pouch according to claim 1, wherein said body is formed from water-permeable sheet material, and said body contains a rehydratable foodstuff selected from the group consisting of cereal grains, pasta and beans. 8. The boil-in-bag pouch according to claim 1, wherein said pleat comprises a first strip of the sheet material folded inwardly towards the front face of the pouch along said only one side of the pouch and a second strip of the material folded inwardly towards the back face of the pouch along said only one side of the pouch, said first and second strips meeting along a fold line located internally of said front and back faces, and respective top and bottom ends of said first and second strips being bonded in face to face relationship with said front and back faces, respectively, at said top and bottom transverse seals. 9. The boil-in-bag pouch according to claim 8, wherein the width of said folded regions, corresponding to the maximum depth of the pleat formed in the said only one side of the pouch, is from about 2 cm to about 6 cm. 10. The boil-in-bag pouch according to claim 1, wherein the top and bottom transverse seals provide end flaps on the pouch from which the contents of the pouch are substantially excluded, wherein the end flaps have a minimum width (measured in the longitudinal direction of the pouch) of from about 1 cm to about 4 cm.
