Grease a 9-inch pan by 13-inch pan. Preheat oven to 325 degrees. Put a layer of pasta in the greased pan. Add a layer of peas, then the tuna. Cover with mushroom soup mixed with cheese and the liquid from the peas. If you have some potato chips crush some and put on top. Cover with foil and bake at 325 degrees for 30-40 minutes or until thoroughly cooked.
