Okay, so looking at this picture is a little painful. But give it a shot. Mysteries lie within.
I’m pretty sure I’ve written before about the Southernism that is “can [product which is in a can].” While it isn’t my preference, I’m not necessarily going to Red Pen it unless I’m in a really bad mood. But here we have three different items (in case you can’t read them, they’re “canned meats,” “can soups,” and “canned fruits”). What is up with that?
Clearly, “can” is being used as an imperative verb form, here. They’re commanding you to combine the ethnic foods, meats and fruits together to make a soup, which you will then can. Mystery managed!
