  • 8 large egg whites (1 cup)
  • ground black pepper to taste (optional)
  • Nonstick cooking spray
  • ¾ cup sliced mushrooms
  • 2 green onions chopped (reserve 1 for garnish)
  • ½ medium tomato chopped (reserve a small amount for garnish, if desired)
  • 2 Tbsp shredded cheddar cheese (1/2 oz.)


  1. Combine egg whites and pepper (if desired) in a small bowl; whisk to blend. Set aside.

  2. Heat small nonstick skillet, lightly coated with spray, over medium heat.

  3. Add mushrooms, green onion, and tomato; cook, stirring frequently, for 4 to 5 minutes, or until tender. Remove from skillet.

  4. Place eggs in same skillet; cook over medium-low heat. Do not stir. As eggs set, lift edges, letting uncooked portion flow underneath.

  5. When eggs are almost set, add mushroom mixture and cheese; cook for 1 to 2 minutes or until cheese starts to melt. Gently fold in half.

  6. Garnish with green onion and tomato, if desired.
