2. Toss zucchini, pepper, mushrooms, and onion with oil. Place in medium skillet over medium-high heat and sauté until veggies are soft and excess liquid has evaporated, about 6 to 8 minutes.
3. Top crust evenly with cheeses. Arrange sautéed vegetables over cheese and top with tomatoes. Bake 18 to 20 minutes until crust is baked through and slightly crisp. Sprinkle with basil. Let stand a few minutes before cutting into quarters.
