Preheat oven to 350 degrees Fahrenheit and grease a muffin tin with cooking oil.
Combine eggs and egg whites in a bowl and sprinkle in salt and pepper. Beat with a fork.
Grate red peppers, spinach, and carrots in a chopper or food processor.
Stir vegetables and cheese into the egg mixture.
Divide between baking cups, filling each about halfway full. Using a 1/4 cup for scooping works well.
Bake for about 20 minutes, until set.
Remove from oven, transfer to a plate or wire rack, and let cool. Enjoy!
