In this Tuna Casserole, add 1 can of cream of mushroom soup, a dash of water to rince out the can with, 1 can of small sweet peas, a small yellow onion chopped up small, and a fist full or two of Lay's Potato chips (plain) crushed up, than mix all this with what was given at first to you in this Tuna Casserole, except salt, pepper and other spices, bake it the same, than watch the smile on peoples faces as they eat this. It's like Grandma use to make.
