• 1 serving cooking spray (optional)
• 1 tablespoon olive oil, or as needed
• 1/2 onion, chopped
• 1/2 red bell pepper, diced
• 4 button mushrooms, diced
• 1 stalk fresh asparagus, trimmed and chopped
• 6 egg whites
• 2 eggs
• 1/3 cup skim milk
• 1 cup shredded Cheddar cheese

1. Preheat oven to 375 degrees F (190 degrees C). Spray an 8-inch square baking dish with cooking spray.
2. Heat olive oil in a skillet over medium heat; cook and stir onion, red bell pepper, mushrooms, and asparagus until onion is translucent, 5 to 10 minutes. Spread onion mixture into the prepared baking dish.
3. Beat egg whites, eggs, and skim milk together in a bowl until smooth; pour over onion mixture. Sprinkle Cheddar cheese over egg mixture.
4. Bake in the preheated oven until frittata is set in the middle and a fork inserted in the middle comes out clean, 20 to 25 minutes.
