Preparation

In a large zip-lock plastic bag or dish with cover, combine lime juice, oil, cumin, chili powder, oregano and pepper; stir well. Add fish to lime marinade and refrigerate at least 30 minutes. Prepare grill (medium-high heat) and oil the rack so fish will not stick. Place fish on the hot grill and cook 4–5 minutes per side or until fish flakes easily when teated with a fork. While fish is cooking, wrap tortillas in foil and place on grill to heat. Place black beans in a microwave-safe dish, cover and heat in the microwave. When fish is done, place it in a dish and flake with a fork. Assemble tacos by spooning beans into the center of each tortilla, add flaked halibut and top with cheese and salsa. (See the recipe for Mango Salsa.) Alternate broiling option: Preheat oven broiler, coat broiler pan with vegetable oil spray and broil fish 4–5 minutes per side.
