Ingredients
- 4 Mahi Mahi fillets
- 1/2 cup soy sauce
- 3 T Rice vinegar, not seasoned
- 2 T sesame oil
- 1/4 cup low-carb sweetener of your choice
- 2 tsp. garlic powder
- 1/4 tsp. Red Pepper Powder
- 2 green onions, thinly sliced
Directions
- If your fish is frozen, move it to the refrigerator to thaw overnight, then drain off any liquid and blot the fillets dry.
- In a small measuring cup, stir together the soy sauce, rice vinegar, sesame oil, sweetener, garlic powder, Red Pepper Powder, and green onion slices.
- Pour half the sauce into a small Ziploc bag, add the fish, and refrigerate it for about 1 hour. A little extra marinating time is fine.
- When it’s time to grill, remove the fish from the refrigerator and allow it to warm to room temperature.
- Coat the grill with non-stick spray or rub it with olive oil, then heat it to medium-high, hot enough that your hand can stay over it for only 2-3 seconds.
- Place the Mahi Mahi on the grill, top side facing down and set diagonally across the grates. Cook for 2-3 minutes, just until grill marks begin to show; lift an edge if you need to peek.
- Turn the fish 90 degrees and grill for another 2-3 minutes so the marks cross.
- Flip the Mahi Mahi and continue cooking for about 3-4 minutes, until it feels firm but not hard when pressed. The full grilling time should stay within 8-10 minutes, so don’t let it go too far.
- Serve the fish hot, with the reserved sauce alongside for dipping.
