In medium bowl, mix beaten eggs and egg whites, the milk, salt, ground red pepper and lemon juice until well blended.
Set oven control to broil. In 8-inch ovenproof nonstick skillet, heat oil over medium-low heat. Pour egg mixture into skillet; sprinkle with parsley. Cover; cook 10 to 15 minutes, lifting edges occasionally to allow uncooked egg mixture to flow to bottom of skillet, until egg mixture is set but still moist on top. Arrange tomatoes over egg mixture.
Broil 6 to 8 inches from heat 1 to 3 minutes. Remove from broiler. Sprinkle both cheeses over top; broil 1 minute longer or until cheeses are melted. Cut into wedges to serve.
