Makes about 15
16 ounces large cremini mushrooms, cleaned
½ cup pizza sauce, heated
Black olives, halved
1 cup grated mozzarella cheese
Grated Parmesan cheese
Preheat oven to 400 F. Line a shallow, rimmed baking pan with parchment or foil. Remove and discard stems from mushrooms. Place mushroom caps on baking pan, and bake 8 minutes. Remove from oven. Turn mushrooms upside down on a paper towel to drain liquid that has accumulated during baking; use another paper towel to dry insides completely. Turn on oven broiler.
Spoon ½–1 teaspoon pizza sauce into each mushroom, followed by pepperoni, olive half and mozzarella. Broil until cheese is melted, about 2–3 minutes. Remove from oven, and let sit for 3–5 minutes before serving. Sprinkle with Parmesan cheese.
