Preheat oven to 425 degrees F. Lightly oil a baking sheet or coat with nonstick spray.
Season zucchini with garlic powder, salt and pepper, to taste.
In a medium bowl, combine milk and egg; set aside.
Working in batches, dredge zucchini rounds in flour, dip into the milk mixture, then dredge in crushed potato chips, pressing to coat. Place zucchini rounds in a single layer onto the prepared baking sheet; coat with nonstick spray.
Place into oven and bake golden brown and crisp, about 22-26 minutes.
Serve immediately, garnished with parsley, if desired.
