This recipe is a great way to utilize leftovers in your refrigerator. If using leftover cooked spaghetti, use about 3 1/2 cups. Use other vegetables you might have, including broccoli florets or cooked cubed potatoes.
Preheat oven to 350 degrees.
Cook spaghetti as directed on package and drain well.
Meanwhile, heat oil in large ovenproof skillet on medium-high heat. Add the mushrooms, bell pepper, and onion. Cook and stir for 5 minutes or until tender. Add the zucchini, tomatoes, rosemary, garlic powder, oregano, thyme, and salt and cook for 10 minutes until most of the liquid has evaporated.
Beat the eggs in large bowl. Add the spaghetti and 1 cup of the cheese and mix well. Stir into the vegetables in the skillet. Cook on medium-low heat for 5 minutes or until bottom is set. Sprinkle with the remaining 1 cup cheese.
Bake for 8 to 10 minutes or until center is just set and cheese is melted. Cut into 8 wedges to serve.
