1 pound ground beef, 1 onion, 1 1/2 tablespoons dried sage, 1 teaspoon paprika, ¼ teaspoon salt, ¼ teaspoon pepper, 1/2 teaspoon garlic powder
Place the toast in the bottom of a 9" x 13" baking dish and layer the cheese slices on top.
6 slices toasted bread, 1/2 pound sharp cheddar cheese
In a large bowl, whisk together the eggs, milk, 1/2 teaspoon salt, and 1/4 teaspoon pepper, and then stir in the browned meat and onions.
12 eggs, 2 cups milk, ½ teaspoon salt, ¼ teaspoon pepper
Pour the egg mixture into the baking dish over the bread and cheese.
