Preheat oven to 375 degrees F. Placed the chopped broccoli, onion, bell pepper, mushroom and garlic powder in a large frying pan with the 2 T EVOO over medium heat. Sauté until broccoli is tender.
Spray a casserole dish with Pam. Spread the cooked vegetables in the bottom on the dish. Let cool for a few minutes.
In a large bowl, whisk the 8 eggs together. Add in the milk and whisk again. Add in the cheese and seasonings and stir gently together.
Pour the egg mixture over the slightly cooled vegetables. With a spoon bring some of the veggies to the top. Bake for 35 minutes, uncovered. Enjoy warm!
