This can be made the night before and kept in the fridge to be baked the next morning or made just before you need it.
1 loaf French bread or Texas toast bread
1/2 c. chopped onion
1 can sliced mushrooms
1 # cooked sausage
12 oz frozen shredded potatoes
2 c. grated cheese
1 1/4 c. milk
Slice french bread, if using that kind. Butter one side of the bread and lay one layer in the bottom of 9 x 13 pan, butter side down. Layer all the other ingredients over the bread except milk and eggs. In a bowl, mix the eggs, milk, salt and pepper to taste. Put another layer of buttered bread on the top of everything, butter side up this time, and pour the egg mixture over the top of everything. Sprinkle additional cheese over the whole thing. Spray foil with Pam and put foil over the pan. Bake at 350° for 45 minutes to 1 hour, or until eggs are set. Remove the foil the last 5 minutes. Serve hot.
