Heat oven to 375° F. Cook sausage in 10-inch nonstick skillet until browned; drain grease. Crumble; set aside.
Meanwhile, separate crescent roll dough into sixteen triangles. On two ungreased 12-inch rimmed pizza pans or large cookie sheets form round pizza shape by placing eight triangles per pan, slightly apart in circle, with tips pointing towards the center. Press dough together to form a well sealed 12-inch circle. Turn up edges of each pizza to form rim.
Sprinkle cooked sausage evenly over each crust. Top with Potatoes, assorted peppers and green onions. Sprinkle with shredded Sharp Cheddar cheese. Stir together eggs, milk, salt and pepper in small bowl. Pour equally over each pizza. Sprinkle with grated Parmesan cheese.
Bake 15-20 minutes or until eggs are set and crust is golden brown.
