Egg White Frittata's - Super Easy Recipe and pretty :) Directions: Grease muffin tin with EVOO and pour in egg whites 1/2 way (I buy them in the carton). Sprinkle in veggies of your choice. I used chopped fresh spinach and red bell pepper, sliced grape tomatoes and mushrooms. Pat the veggies down into the egg whites with a spoon and bake 15-20 minutes at 375. Voila! Great for grab and go in the morning with a slice of Ezekiel toast or chopped inside an Ezekiel tortilla.
