- 1/4 cup vegetable oil
- 1 jalapeño chile, seeded and finely chopped
- 1 small red onion, one-quarter finely chopped, the remainder thinly sliced
- 1 clove garlic, grated or finely chopped
- One can black beans (15 ounces), rinsed
- 1 teaspoon ground cumin
- Salt and pepper
- 3 tablespoons honey
- 2 tablespoons hot pepper sauce
- Juice of 2 limes, plus 2 teaspoons grated peel
- 1/2 head red cabbage, shredded
- 1/3 cup finely chopped cilantro (a generous handful)
- Four mahi mahi fillets (6 ounces each)
- 8 corn taco shells
- 8 flour tortillas
- 1 cup crème fraîche or sour cream
In a medium skillet, heat 1 tablespoon oil over medium heat. Add the jalapeño, chopped red onion and garlic and cook for 4 minutes. In a small bowl, mash the black beans with the cumin and season with salt and pepper; cover.
In a large bowl, combine 2 tablespoons oil with the honey, hot sauce and lime juice; season with salt and pepper. Add the sliced onion, cabbage and cilantro; toss.
Pre-heat a grill or grill pan to medium. Coat the fish with the remaining 1 tablespoon oil and the lime peel. Cover and grill the fish, turning once, for 8 minutes.
Warm the taco shells and tortillas on the grill. Spread a few spoonfuls of mashed beans (stir 1 to 2 tablespoons hot water into the beans if too thick) on the outside of the tacos, and wrap a tortilla around each one, pressing to adhere.
Flake half a piece of fish into each taco shell and top with some cabbage slaw. Serve 2 tacos per person, with the crème fraîche and extra slaw on the side.
