1 pkg. frozen spinach
1 lb. mild sausage
4 eggs
1 can evaporated milk
1 c. grated cheddar cheese
4 tbsp. grated Parmesan cheese
1/3 c. chopped onion (optional)

Cook spinach and sausage as usual, separately. Drain all grease from sausage. Drain all water from spinach. Combine eggs and milk; blend until well mixed. Place spinach and sausage in a 9 inch pyrex dish and top with grated cheddar cheese. Pour egg mixture over sausage and cheddar cheese. Shake on Parmesan cheese.

Bake at 350°F for 35-40 minutes or until eggs do not run when cut.
