This is a receipe my mom used to make. She usually used leftover pork chops in it. Was always a good hot casserole.
1 lb cubed pork, browned
1 can tomato soup (set aside about 1/4 of the can)
1 small jar Cheese Whiz (set aside about 1/4 jar)
1/4 cup diced onion
10 oz. cooked egg noodles
Mix all of the above together in a casserole dish. Top casserole with remaining soup and cheese. Bake at 325 for 30 minutes.
