Preheat your oven to 350 degrees F. Then, heat a medium frying pan on medium-high heat. Place olive oil in the pan—Cook vegetables for about 5 minutes or until tender.
If using a metal muffin pan, coat with non-stick cooking spray.
Place an equal amount of the cooked vegetable mixture, quinoa, and feta cheese in each muffin cup.
Pour in egg whites until the muffin cup is nearly full. Top with Italian herbs and pepper and salt.
Bake for 20-25 minutes or until the center is firm.
Let cool before removing from the pan. Enjoy!
