Remember the old punch line, "Orange you glad I didn't say banana?"
That's really the only food pun I can think of off the top of my head, but there are infinite 'punny' possibilities when it comes to the grocery aisle. How do I know this? A man recently went out shopping with his girlfriend and took his camera out to film the experience. He then proceeded to torture her with the most cringe-worthy food puns, and it's so, so funny. His girlfriend is both amused and annoyed by the whole thing.
