1/4 cup grated or shredded cheese like Parmesan, cheddar or mozzarella
2 large slices whole wheat or sourdough bread
In a bowl, whisk together eggs, milk, salt and pepper. Mix in vegetables and cheese. Set aside.
Using a large mouth glass or a knife, cut a large circle or rectangle (with knife) in the center of each bread slice and remove the bread shape (save to make breadcrumbs or croutons.)
Coat a frying pan with cooking spray and place over medium heat.
Place both bread slices in pan and immediately fill the middles with the egg mixture. Cook for about 2 minutes and then using a spatula, carefully flip. Cook for an additional 2 minutes or until the egg mixture is set. Remove from pan and enjoy!
