These little frittatas are so easy to make and have such great flavor. They are so good for breakfast, brunch, a light lunch, an appetizer or for a quick snack. They are very versatile, too, as you can use your favorite ingredients.
Preheat oven to 350°. Spray muffin cups well with cooking spray. Beat eggs, milk, salt and pepper in medium bowl. In a skillet, add EVOO and sautè onion and bell pepper until tender; cool. Add cheese, sour cream, bell pepper, and spinach (or whatever green vegetable you are using) to the egg mixture and mix well. Add about a 1/4 cup of the egg mixture to each muffin cup (or fill muffin cup 3/4 full). Bake in preheated oven 20-22 minutes until egg mixture is set. When done, remove from cups onto serving plate. (In my oven, 20 minutes was just right). This makes about 10 - 12 muffin frittatas. I have added finely chopped 98% fat free ham to the egg mixture.
