In a skillet over medium heat, sauté the shrimp with cumin and chili powder until they are cooked through and opaque. Set aside.
Prepare the salsa by mixing diced mango, finely chopped red onion, chopped cilantro, and freshly squeezed lime juice in a bowl. Stir well to combine all the ingredients.
Warm the tortillas in a dry skillet or the oven until they are soft and pliable.
Assemble the tacos by placing some cooked shrimp on each tortilla, then topping with the mango salsa.
Serve the tacos immediately, garnished with additional cilantro and lime wedges if desired.
Enjoy your delicious shrimp and mango salsa tacos!
