1 big box pasta shells
1 (8 oz.) pkg. button mushrooms, sliced
1 med. onion (chopped)

Set cream cheese out to soften. Saute mushrooms and onions while you are cooking pasta. When pasta is done, drain. Then add onion, butter and mushroom mixture, cubed ham and cream cheese. Cut cream cheese into thin slices before you add it. Stir until thoroughly mixed, then serve.
