the first side end flap has a male locking feature, a female locking feature interrupts the second fold line, and engagement of the male locking feature and the female locking feature secures the first side end flap to the back panel.

2. The carton of claim 1 , wherein the male locking feature is a locking tab and the female locking feature is a cut.

3. The carton of claim 1 , wherein the first side end flap comprises a base portion foldably connected to the front panel and a distal portion foldably connected to the base portion, the male locking feature is formed on a distal edge of the first side end flap.

4. The carton of claim 1 , wherein the male locking feature is a first male locking feature, the female locking feature is a first female locking feature, the second side end flap comprises a second male locking feature and the carton further comprises a second female locking feature in the first side end flap.

5. The carton of claim 4 , wherein engagement of the second male locking feature and the second female locking feature secures the second side end flap to the front panel.

6. The carton of claim 5 , wherein the first side end flap comprises a base portion foldably connected to a distal portion at an oblique fold line.

7. The carton of claim 6 , wherein the first female locking feature interrupts the oblique fold line.

8. The carton of claim 4 , wherein the first side end flap and the second side end flap are in at least partial face-to-face contact to form a side panel of the carton.

9. The carton of claim 8 , wherein the second side end flap overlaps the base portion of the first side end flap.

10. The carton of claim 9 , wherein the side panel is a first side panel of the carton, and the carton further comprises a third side end flap foldably connected to the front panel and a fourth side end flap foldably connected to the back panel, the third side end flap and the fourth side end flap are in at least partial face-to-face contact to form a second side panel of the carton.

11. The carton of claim 10 , wherein the third side end flap comprises a base portion foldably connected to the front panel and a distal portion foldably connected to the base portion of the third side end flap, the fourth side end flap overlaps the base portion of the third side end flap.

12. The carton of claim 10 , wherein a free edge of each of the first side end flap and the second side end flap defines a respective first angled leg and a second angled leg of the carton.

13. A blank for forming a carton for holding at least one food product, the blank comprising:
a plurality of panels for extending at least partially around an interior of the carton formed from the blank, the plurality of panels comprising a bottom panel, a front panel, and a back panel; and
a first side end flap foldably connected to the front panel at a first fold line, a second side end flap foldably connected to the back panel at a second fold line, the front panel, the back panel, the first side end flap, and the second side end flap are for cooperating to form an open top of the carton formed from the blank for accessing the interior of the carton formed from the blank,
the first side end flap has a male locking feature, a female locking feature interrupts the second fold line, and engagement of the male locking feature and the female locking feature secures the first side end flap to the back panel when the carton is formed from the blank.

14. The blank of claim 13 , wherein the male locking feature is a locking tab and the female locking feature is a cut.

15. The blank of claim 13 , wherein the first side end flap comprises a base portion foldably connected to the front panel and a distal portion foldably connected to the base portion, the male locking feature is formed on a distal edge of the first side end flap.

16. The blank of claim 13 , wherein the male locking feature is a first male locking feature, the female locking feature is a first female locking feature, the second side end flap comprises a second male locking feature, and the carton further comprises a second female locking feature in the first side end flap.

17. The blank of claim 16 , wherein engagement of the second male locking feature and the second female locking feature secures the second side end flap to the front panel when the carton is formed from the blank.

18. The blank of claim 17 , wherein the first side end flap comprises a base portion foldably connected to a distal portion at an oblique fold line, the first female locking feature interrupts the oblique fold line.

19. The blank of claim 13 , wherein the first side end flap comprises a base portion foldably connected to the front panel and a distal portion foldably connected to the base portion of the first side end flap, and the blank further comprises a third side end flap foldably connected to the front panel and a fourth side end flap foldably connected to the back panel, the third side end flap comprises a base portion foldably connected to the front panel and a distal portion foldably connected to the base portion of the third side end flap.

20. A method of forming a carton for holding at least one food product, the method comprising:
obtaining a blank comprising a plurality of panels comprising a bottom panel, a front panel, and a back panel, a first side end flap foldably connected to the front panel at a first fold line, a second side end flap foldably connected to the back panel at a second fold line, the first side end flap has a male locking feature, and a female locking feature interrupts the second fold line;
folding the plurality of panels at least partially around the interior of the carton;
folding the first side end flap and the second side end flap such that the front panel, the back panel, the first side end flap, and the second side end flap cooperate to form an open top of the carton for accessing the interior of the carton; and
