Cut zucchini and squash in half lengthwise, then slice into 1 inch pieces, place squash, zucchini, onion, garlic, red pepper, and salt & pepper into a bowl, mix well. Lightly spray 9x13 inch pan with cooking spray, pour ingredients into baking dish. Drizzle with olive oil. Place in pre-heated 450 degree oven, and bake for 20 minutes or until veggies are fork tender. Remove from oven, sprinkle with both cheeses and fresh basil. Enjoy!
I usually slice my zucchini and squash into fourths lengthwise. This way you get more bite size pieces.
