1Heat oven to 400°F. Spray 10-inch nonstick skillet with cooking spray; heat over medium heat. Cook sausage in skillet about 3 minutes, stirring occasionally, until brown; drain. Remove sausage from skillet; set aside.
2Pour eggs into skillet. As mixture begins to set at bottom and side, gently lift cooked portions with spatula so that thin, uncooked portion can flow to bottom. Do not stir. Cook 4 to 5 minutes or until eggs are thickened throughout but still moist.
3Place pizza crusts on ungreased cookie sheets. Sprinkle with half of the cheese. Top each with eggs and sausage. Sprinkle with remaining cheese. Bake 10 to 12 minutes or until cheese is melted.
