Heat a medium skillet over medium heat.
Add to skillet broccoli, mushrooms, red pepper, and orange pepper. Sauté about 5 minutes until the veggies begin are soft.
Add spinach and cook another 2 minutes to wilt the spinach.
While the veggies are sautéing, in a medium mixing bowl add the eggs, milk, pepper, and salt.
Whisk to completely blend the eggs. The longer the eggs are whisked, the fluffier they are when cooked.
Add the egg mixture to the veggies. Let cook about 1 minute until eggs begin to set.
Push the eggs towards the center of the pan and gently fold over. Tilt pan slightly to allow the liquids to cook through. Continue to do this until the eggs are just about set. If adding cheese, do so now.
Remove from heat and let rest one minute. Serve and enjoy.
