Place sausage on a 15-by-10-by-1-inch baking pan. Bake at 375 degrees for 15-20 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 for 20-25 minutes, or until a knife inserted near center comes out clean.
