Halloween Chicken Pizza Masks

Heat frypan to medium-high temperature. Add ground chicken and onion; cook, stirring, until all red is gone, about 6 minutes. Set aside. With aluminum foil, cover 10 1/2 x 15 1/2-inch baking pan. Spread each muffin half with 1/2 teaspoon margarine and arrange in single layer on prepared pan. Spread heaping tablespoon pizza sauce on each muffin half. Cover generously with ground chicken and onion; sprinkle with oregano. Cut 12 slivers of green pepper into "smiling" mouth shapes and set aside; chop remaining pepper and sprinkle on pizzas. Mix together Cheddar and mozzarella cheeses; sprinkle generously on mini-pizzas. Bake in 450°F (230°C) oven about 12 minutes. Remove from oven. Make mask face on each pizza by using 2 ripe olive rings for eyes and pepper slice for mouth. Turn some slices up for smiles and some down for frowns.
