In a medium-sized mixing bowl, combine 2 tablespoons of minced ginger, 3 cloves of minced garlic, and 2 chopped scallions. Mix in the juice of one lemon and 3 tablespoons of olive oil, followed by a pinch of salt and pepper. Whisk until well blended.

Place the swordfish steaks into the marinade, coating each piece generously. Cover and let marinate at room temperature for at least 15 minutes.

Preheat your grill or oven to 400°F (200°C). If using a grill, grease lightly to prevent sticking. Line a baking sheet with parchment paper if using the oven.

Arrange the marinated swordfish steaks on the grill or baking sheet. Cook for about 6-8 minutes per side until the fish is opaque and flakes easily with a fork.

Remove the cooked swordfish from the heat, let it rest for a minute, then plate and garnish with additional chopped scallions and lemon wedges.
