I love crustless quiches because they're easy to prepare and they make a delicious high protein meal. The ingredients in this flavorful spinach quiche include Cheddar cheese, bacon, and seasonings.

Serve this quiche with a cup of soup, baked beans, or a simple tossed salad for a fabulous lunch, brunch, or evening meal. Feel free to sauté 1/2 to 1 cup of sliced fresh mushrooms with the onions.

  4. Pour off all but about 1 teaspoon of the bacon grease. Save the bacon grease to use in cornbread or for a flavorful fat for sautéing onions or other vegetables.
