Place sausage on a 15 by 10 by 1-inch baking pan. Bake at 375° for 15 to 20 minutes or until sausage is no longer pink, turning once; drain and slice into 1/2-inch coins. Unroll crescent roll dough; separate into eight triangles. Arrange on an ungreased 12-inch pizza pan, placing points to the center. Press seams together and press over the bottom and up the sides of pan to form a crust. Top with hash browns, sausage and cheddar cheese. Combine eggs, milk and spices; pour over cheese. Sprinkle with Parmesan cheese. Bake at 375° for 20 to 25 minutes, or until a knife inserted near center comes out clean.
