Stuffed Mushrooms
["1 (16 oz.) pkg. fresh mushrooms (I prefer the large size)", "1 small onion, finely diced", "1 stick butter", "4 to 6 oz. pepperoni, finely diced", "1 to 1 1/2 c. Italian bread crumbs", "6 oz. finely shredded Parmesan cheese"]
["Gently wash mushrooms; remove stems.", "Finely dice stems; set aside.", "Place mushroom caps, open end up, in a large flat casserole.", "Melt approximately 1/2 of the stick of the butter. Add the onion and mushroom caps.", "Lightly saute until golden. Remove from heat; add the diced pepperoni and bread crumbs, mixing well.", "(I usually use 1 cup of crumbs first to see how well the mixture holds together.", "If I need more, I use more.)", "Stir in the shredded cheese.", "Stuff the mushroom caps; drizzle with the remaining melted butter.", "Bake in a 350\u00b0 oven for about 12 to 15 minutes, or until cheese melts in topping and mushrooms are light golden brown.", "You can also broil these appetizers at 425\u00b0 for about 5 to 8 minutes.", "Serves 16 to 25."]
