Preheat oven to 325 degrees. Fill a shallow 13x9 baking dish with 1/4 inch of water.
Mince the mushroom stems and saute them in a skillet with the margarine, onion, bell pepper, and garlic. Saute over low heat until the vegetables are cooked through and most of the liquid has evaporated.
Meanwhile, toast the bread until it is light brown and toasted all the way through, then crumble the bread into crumbs. Add the bread crumbs, cheese, parsley, salt, pepper, and oregano to the vegetables and mix well. Add the broth and stir to moisten the mixture. Remove from the heat and allow the mixture to cool enough to handle.
Fill the mushroom caps with the mixture and carefully place them in the baking dish. Bake for 25 minutes, until they are cooked through.
