1. Preheat oven to 500 degrees F. Thoroughly pat flounder dry with paper towels and set aside. Line a baking sheet with foil and spray with vegetable cooking spray.
2. Combine cornflake crumbs, chili powder, cumin, paprika, and onion powder in a mixing bowl and whisk until evenly blended.
3. Place fish on baking sheets and spray fish with vegetable cooking spray. Evenly sprinkle crumb mixture over fish, gently pressing it into the flesh.
4. Bake fish for 6 to 8 minutes or until cooked through — it should be opaque and flake easily. Using a spatula, transfer to a serving platter. Garnish with lime quarters and, if using, cilantro. Serve immediately.
