Before adding egg mixture, you may sprinkle bread shell with chopped cooked ham or chicken; crumbled cooked sausage; or chopped vegetables.
Place bread shell on a baking sheet, and sprinkle with shredded cheese and bacon.
Whisk together eggs and milk until well blended; pour over center of bread shell.
Bake at 400° for 12 to 15 minutes or until egg mixture is set and cheese is golden brown. Cut into wedges, and serve immediately.
