These Zesty Grilled Fish Tacos are a delightful twist on the classic recipe, featuring a tangy lime marinade and a refreshing cucumber relish.
Combine olive oil, juice from two limes, chili powder, and black pepper in a pie pan.
Use a whisk to ensure the marinade is well mixed for even flavor distribution.
Coat the halibut fillets in the marinade and refrigerate for 15 minutes.
Refrigerating allows the flavors to penetrate the fish for a more robust taste.
Dice the cucumber and red onion, then mix with sugar and a pinch of salt in a bowl.
Let the relish sit for a few minutes to allow the flavors to meld together.
Grill the halibut fillets over medium-high heat for 4 minutes per side.
Ensure the grill is preheated to prevent the fish from sticking.
Warm the tortillas on the grill for 30 seconds per side and keep them wrapped in foil.
Warming the tortillas makes them more pliable and enhances their flavor.
Assemble the tacos by placing a portion of grilled fish, a spoonful of relish, and a drizzle of sour cream on each tortilla.
Serve immediately to enjoy the tacos at their freshest.
