Stuffed Mushrooms

I threw this together one night when I couldnt find a recipe for stuffed shrooms and my internet was down. They are meatless yet fabulous!

12oz pkg Portabella mushrooms
1/4 cup chopped mushroom stems
1/4 cup chopped onions
1/4 cup chopped green peppers
1 t minced garlic
1/2 cup bread crumbs (i made mine fresh by toasting a hot dog bun)
1/2 t oregano
1/2 t parsley
1 T parmesan cheese (grated)
1/4 cup mozzarella cheese (shredded)
2 T melted margarine

Topping
2 T melted margarine
more mozzarella cheese

1. Remove stems and gills from mushrooms
2. Mix all ingredients and stuff into mushrooms
3. Pour 2T melted margarine over shrooms, sprinkle with mozzarella cheese (however much you want... we make ours very cheesey, but a little will do.
4 Bake at 400 for 20 minutes
