Preheat oven to 400°F. Lightly spray star-shaped pan cavities with vegetable pan spray. Divide dough into 12 pieces.
Press dough into each prepared cavity. Use fork to prick dough; brush with olive oil. Bake 5 minutes. Cool slightly.
Mix ricotta cheese, 1/4 cup Parmesan cheese, garlic, salt and crushed red pepper. Top baked crusts with spinach and spoonfuls of cheese mixture. Sprinkle with remaining 1/4 cup Parmesan cheese. Bake 5-10 minutes or until cheese is melted and spinach is heated through.
