Heat oven to 400 degrees.
Grease a glass loaf pan.
Brown 2 sausage patties with 1/4 cup chopped onion and crumble the meat. Drain any grease.
Stir together the sausage/onion mixture, 3/4 cup hash browns, and 1/2 cup shredded cheese and put in loaf pan.
In a bowl, mix 1/4 cup flour, 1/2 cup milk, 1/16 teaspoon pepper, and 1 egg. Pour over the mixture in the loaf pan.
Bake uncovered for 20 minutes or until a knife inserted in the center comes out clean. Cool five minutes before serving.
This makes 2 big servings that should hold you until lunch time. If you only eat part of it, refrigerate the rest and heat it in the microwave for another time.
