Easy Crustless Quiche

I saw a version of this on Pinterest and decided to make it tonight. It was so easy, quick and delicious. And I didn't have to feel guilty about eating it since it was mostly protein and veggies :) 

Ingredients: 

6 eggs, scrambled

1/2 cup frozen, chopped spinach- defrosted and squeezed dry

1/2 cup grape tomatoes, halved

1/2 cup reduced fat mozzarella cheese, grated

salt and pepper to taste

Spray a pie pan with cooking spray. Combine all ingredients except cheese and pour them into the pan. Sprinkle cheese on top. Bake at 350 for 25-30 minutes.
