Pat the grouper fillets dry with paper towels. In a small bowl, mix the paprika, garlic powder, salt, and black pepper. Rub the spice mixture onto both sides of the fillets.

Heat the olive oil in a large skillet over medium-high heat. Add the fillets and cook for 3-4 minutes per side, or until the fish is golden and flakes easily with a fork. Remove the fillets from the skillet and set aside.

In the same skillet, heat 1 tablespoon of olive oil over medium heat. Add the onion, ginger, and garlic, and sauté for 2-3 minutes until fragrant and softened.

Stir in the chili or red pepper flakes, then add the coconut milk, soy sauce, honey, and lime juice. Simmer for 5-7 minutes, stirring occasionally, until the sauce thickens slightly.

Return the cooked grouper fillets to the skillet, spooning the sauce over the fish. Simmer for 2-3 minutes to let the flavors meld.

Sprinkle with chopped cilantro and optional garnishes like mango slices, toasted coconut, or extra lime wedges.
