Preheat oven to 450. Combine all veggies into large mixing bowl.

Add olive oil and toss veggies to coat. Spread veggies out on large baking sheet; make sure not too crowded.

Bake for 25 minutes, then stir. Cook for another 20 minutes or until veggies are soft and caramelized. Sprinkle with salt and pepper and crushed red pepper.
