Preheat oven to 350ºF.
Finely chop your veggies and sauté them. I used a medley of onion, zucchini, and mushroom. Take the time to brown your onions -- that will help you achieve a great depth of flavor!
In a large bowl, mix your veggies with eggs, pizza sauce, cheeses, and seasonings. Use more or less cheese and sauce based on how you like it.
Grease a round pie pan with olive oil and fill with mixture.
Bake for 20 minutes or until set.
