Stuffed Portobello Mushrooms

Classic stuffed mushrooms can be jazzed up with a variety of ingredients. Try adding crabmeat, bacon, cream cheese, pesto, or blue cheese to the filling in this recipe. Or wrap the (unbroiled) stuffed mushrooms in puff pastry or phyllo dough and bake 15 minutes for a more substantial appetizer.
