Beans in molasses, with bits of what looks like pork.
In-game description

Pork and beans is a type of canned food.

This can requires a can opener, hunting knife, or hatchet to be opened while retaining its full content. It is also possible to smash the can open, but this will result in losing some of its contents to spillage.

Pork and beans can also be warmed up using a fire. This provides a bonus against cold.
