In a mixing bowl, whisk together ½ cup honey, 2 tablespoons olive oil, 2 tablespoons lime juice, and 2 finely chopped jalapeños until smooth and well combined. Add 1 teaspoon garlic powder, a pinch of salt, and a dash of black pepper to enhance the flavors.

Place the mahi mahi fillets into a shallow dish and pour the honey jalapeño marinade over them, ensuring each fillet is evenly coated. Cover and refrigerate for at least 30 minutes.

Preheat your grill or grill pan to medium-high heat, around 425°F, for about 10-15 minutes.

Carefully place the marinated mahi mahi fillets on the grill, allowing space between them. Grill for 4-5 minutes on each side until golden brown and flaky.

Transfer the grilled mahi mahi to a serving platter and drizzle with any remaining marinade. Garnish with sliced jalapeños or lime wedges.
