In a small bowl, beat the eggs until they loosen up. Add the half and half, and green onions. Mix well, highly season with salt and pepper and set aside.
Butter a 12 by 10-inch baking pan. Line the pan with the bread, cutting and rearranging, if needed. Sprinkle the bread with the cooked sausage and cheese. Pour the egg mixture over the entire pan. Cover and refrigerate overnight.
Preheat oven to 350 degrees. Cook covered for 25 to 30 minutes or until the egg mixture is set.
