Tuna Noodle Casserole by curly

Boil a pound of egg noodles or other pasta (preferably not long noodles like spaghetti, but whatever)
Mix in one can cream of mushroom (or chicken or celery or whatever) soup
Add one bag frozen peas or other mixed vegetables
Add one can tuna
Mix it all up
(Some people like to top it with cracker crumbs, if you have them)
Pour mixture in buttered baking pan and bake at 375 for 30 minutes.

You can change any of it, too. It occurs to me that you could make it with sardines in tomato sauce instead, and add fresh tomatos, onion, parsley, and celery (maybe capers) and use tomato soup instead. It's really flexible.
