  • To prepare the salsa in a bowl combine mango, avocado, red onion, lemon or lime juice, olive oil and pickled ginger. Mix to combine, season to taste with salt and pepper and set aside.
  • In a large bowl gently toss sliced carrot, radish, cucumber and sprouts. Pour over remaining basting sauce/dressing, toss, garnish with cilantro and basil, season to taste with salt and pepper and set aside.
  • Preheat grill to high (about 450-500°F).
  • Combine black pepper, sesame seeds and kosher salt. Mix well and crust tuna steaks, on all sides, gently pressing the spices into the fish to adhere.
  • Grill tuna over direct heat for 1 to 2 minutes, per side, until just rare, basting with reserved ½ cup of dressing/basting liquid. Remove from grill, cool slightly and slice each tuna steak into 4.
  • To assemble the taco place one quarter of the watercress into the bottom of the taco shell. Place a layer of salad into the taco and top with sliced grilled tuna. Garnish with salsa. Repeat with remaining grilled tuna and taco shells and serve.
