Veggie Omelet with Toast

In a small bowl, whisk together eggs, milk, salt and pepper. Coat a small skillet with cooking spray; heat over medium heat. Pour in egg mixture and tilt skillet so bottom is completely covered with egg. Cook omelet until eggs are almost set, occasionally lifting egg in skillet to let uncooked egg move to edges of skillet, about 3 to 5 minutes. Top half of omelet with cheese and vegetables; fold omelet in half over fillings and heat through. Serve with toast and tea.
