Low-fat veggie and cheddar cheese frittata

Directions

1. Place oven rack about 8 inches from broiler and preheat oven to 375 degrees F.
2. Heat 1 teaspoon of the oil in a large oven-safe skillet over medium. Add spinach, diced tomatoes, and garlic. Sauté for 4 minutes.
3. In a large bowl, whisk eggs and egg whites. Stir in spinach mixture and cheese; season with salt and pepper.
4. Heat the remaining 2 teaspoons of oil in the same pan. Add egg mixture, reduce heat to low, and shake pan to level ingredients. Place pan in oven; bake for 10 minutes, until eggs are just set. Turn oven to broil; place pan on rack under broiler for 2 minutes, until just browned. Remove from heat, slice into four pieces, and serve with sliced tomatoes and pepper.
