In a bowl, combine the coconut milk, lime zest, lime juice, ground cumin, garlic powder, chili powder, salt, and pepper. Mix well.
Add the shrimp to the marinade, making sure all the shrimp are well coated. Let marinate for about 15-20 minutes.
Heat a pan over medium-high heat. Once hot, add the shrimp along with the marinade to the pan. Sauté for about 5-7 minutes or until the shrimp are pink, opaque, and cooked through.
While the shrimp are cooking, warm the corn tortillas in a separate pan or directly over the flame for a few seconds on each side until pliable.
To assemble the tacos, place a few pieces of sautéed shrimp on each tortilla. Top with shredded cabbage and a spoonful of mango salsa.
Garnish with fresh cilantro and a squeeze of lime juice before serving.
