LOL!
I don't have a solid suggestion for you, but I like your son's sense of humor.
Honestly, if I had those I would probably open up a can and enjoy on crackers for lunch, but then I'm a sardines on crackers for lunch kind of girl. If I felt like sharing with my husband (and he was willing, because he is NOT a sardines on crackers, or any other way, kind of guy), I would stir-fry some mild flavored vegetables that wouldn't detract from the fish flavors, add them to a bed of rice, and top it with the fish and whatever sauce/oil is in the can. Hopefully someone will come along with more inspired ideas for you to use your well-deserved gift. Enjoy! :)
