Frittatas are a simple and delicious low calorie breakfast or lunch. I often use leftovers vegetables and egg whites from a container to make my Frittatas. It is a simple process to make and they can be kept in the frig for a couple of days to be eaten another day. You can use your imagination to make many different types of Frittatas. I had some left over asparagus and panacea (just a tablespoon or so) to make this delicious snack.
