Place the cilantro, garlic, scallions, orange zest, orange juice, sherry vinegar, olive oil, salt and pepper into the bowl of a food processor.
Pulse until the marinade ingredients are finely chopped and the consistency of a thick sauce.
Make the Grilled Swordfish Kebabs with Citrus Herb Salsa
In a large, glass bowl, stir in 3 tablespoons of the Swordfish Marinade to the prepared swordfish. Make sure the swordfish is evenly coated with the marinade. Place in the refrigerator to marinate for about 30 minutes.
If using wooden skewers, soak in water for 30 minutes to prevent burning.
When ready to grill, preheat the grill to high. Thread the swordfish onto prepared wooden or metal skewers. Season lightly with salt and pepper.
Grill the swordfish kebabs for about 3 minutes per side, or until the swordfish is cooked through.
While the swordfish cooks, finish the salsa by combining remaining swordfish marinade with oranges, scallions, garlic, and Fresno chili, if using. Season to taste with salt and pepper.
When the swordfish is grilled, remove from grill and serve with salsa. Enjoy!
