Coat a large skillet with nonstick spray and heat the oil over medium heat.
Sauté the garlic in the olive oil in the hot skillet for 1 minute. Stir in the broccoli, mushrooms and sun-dried tomatoes. Sauté for 2 minutes longer. Reduce the heat to medium-low. Cook, covered, for 2 minutes or until the broccoli is tender-crisp, stirring occasionally. Remove the sautéed vegetables to a bowl. Using paper towels, wipe out the pan.
Coat the skillet with nonstick spray. In a medium bowl, whisk together the eggs, egg whites, milk, salt and pepper until blended. Heat the skillet to medium-high and add the egg mixture. Stir in the broccoli mixture and scramble until cooked through.
Spoon the egg mixture onto serving plates and sprinkle with goat or feta cheese. Serve immediately.
