Trim and quarter zucchinis. Place in a bowl and coat with olive oil. Season with garlic powder, sea salt, pepper. Roll zucchini pieces until coated on all sides with spices and olive oil. Place zucchini in a pie plate or baking sheet skin side down and shred parmesan or asiago cheese on top of each piece.
Preheat oven to 400 degrees and roast zucchini until golden brown on top & cheese bubbly. About 15-20 minutes depending on thickness.
Use same method but without the cheese as well for a lighter side dish.
