On a large baking sheet, toss veggies with olive oil. In small bowl, combine dry seasonings together and sprinkle over top veggies. Sprinkle hot sauce over top if desired. Toss again to coat veggies evenly in seasonings. Bake 7-10 minutes or until edges get slightly crispy and dark. Remove from oven.
Wrap corn tortillas in damp paper towels and microwave 30 seconds to 1 minute or until hot and pliable.
