Veggie Cheese Egg Bake

Our sister-in-law Erin made this for the family when we went away together for Thanksgiving a couple of years ago. It is a great thing to make for a big group of people because you can do it ahead of time and then put it in the oven in the morning.

3 c. shredded cheddar cheese
3 c. shredded mozzarella cheese
1/2 c. sliced mushrooms
1/3 c. sliced green onions
1/2 c. chopped red and green peppers
1/2 c. flour
1 3/4 c. milk
8 eggs
pepper, to taste

optional - cooked, chopped breakfast meat of choice

Preheat the oven to 350. Lightly spray a 9x13 baking dish with cooking spray. In a large bowl, combine cheeses. Sprinkle half the cheese mixture on the bottom of the pan. Lightly spray skillet with cooking spray, heat over med-high heat. Add mushrooms, green onion, and red and green peppers, cook until veg. are tender and soft, about 5-8 minutes. {if using meat, add cooked meat to cooked veggies}. Spread vegetable mixture over cheese, top with remaining cheese. In large bowl, combine flour, milk, eggs and pepper. Pour over the top of cheese. Bake for 35-40 minutes or until mixture is set and lightly browned. Let stand at room temperature for 10-15 minutes before cutting into squares.
