Fontina is a creamy, mild cheese whose mellow flavor blends well with the sweet caramelized onions. If you prefer, mozzarella can be substituted for fontina.
Olive oil-flavored cooking spray
1 teaspoon olive oil
3 cups thinly sliced sweet onion (about 2)
1 (8-ounce) package pre-sliced mushrooms
1 teaspoon minced fresh rosemary
1/2 teaspoon salt
1/4 teaspoon pepper
1 (10-ounce) thin Italian cheese-flavored pizza crust (such as Boboli)
2/3 cup (2.6 ounces) shredded fontina cheese
How to Make It
Heat oil in a nonstick skillet coated with cooking spray over medium heat. Add onion; sauté 20 minutes or until golden. Add mushrooms and rosemary; sauté 10 minutes. Sprinkle with salt and pepper; stir well.
Preheat oven to 450°.
Place pizza crust on a large ungreased baking sheet. Lightly coat crust with cooking spray. Spread onion mixture evenly over crust; sprinkle with cheese.
Bake at 450° for 15 minutes or until cheese is bubbly. Cut into 8 slices.
