6-8 med  Portabella Mushrooms
4 tbs  Butter
8 oz  Cream Cheese (also works with Lite cream cheese)
4-5 strips  Bacon, cooked until crisp, cooled and crumbled
1/2 C  Mozzarella cheese (or cheese of your choice)

Sauté mushroom caps in 4 tablespoons of butter for about 5 minutes, save the remaining butter. Place caps in an oven-proof dish. Mix cream cheese and bacon, and top mushrooms caps, heaping the mix a little. Top with grated cheese. Pour the remaining butter from sautéing around mushrooms and bake for about 8-12 minutes at 375F degrees. Cheese on tops should be melted. Best when served warm.
