Dude! That casserole was good! Huh.
So here: Boil some shell or macaroni pasta for five minutes. Drain, lay in the bottom of a 9x13 glass dish. On top of that, add a can of drained beans (I used white, you could use black or anything you like), and then a can of drained tuna, then a can of mushroom soup (I like Amy's because it has no MSG, which I'm deathly allergic to, unlike most other brands), then some frozen green peas, a chopped scallion, then top with grated sharp cheddar. Bake covered with foil at 350 degrees for 30 minutes, uncovered for 5 minutes. Weirdly good.
