2 c. cooked macaroni
4 tbsp. flour
Salt
Pepper
1 can stewed tomatoes

Slice up Cheddar cheese and put in microwaveable casserole (2 quart). Sprinkle with flour, salt, and pepper. Pour milk over cheese. Cover. Put in microwave for 5 minutes or until cheese is melted and creamy when stirred. Stir in stewed tomatoes. Add macaroni.
