Instructions

  1. Cook and drain macaroni. If using the optional chopped celery, boil it with the pasta.
  2. In a bowl blend together the soup, milk, mayo, and dry mustard.
  3. Stir in cheese, tuna, and pimiento.
  4. Gently fold in macaroni/spaghetti and transfer into a 2 quart 8X8 inch casserole dish.
  5. Combine crumbs, butter, and paprika and sprinkle evenly on top.
  6. Bake uncovered at 350 for 30-35 minutes or so. When the crumbs are a pretty color and the juices are bubbling around the edges your casserole is done.
