Prep the Shrimp: In a bowl, toss shrimp with olive oil, chili powder, cumin, smoked paprika, garlic powder, salt, and lime juice. Let it marinate while you make the salsa.
Make the Mango Salsa: Combine mango, red onion, bell pepper, jalapeño, cilantro, lime juice, and a pinch of salt. Stir and set aside.
Cook the Shrimp: Heat a large skillet over medium-high heat. Add shrimp in a single layer and cook for 2-3 minutes per side, until pink and just cooked through.
Warm the Tortillas: While the shrimp cooks, warm tortillas in a dry skillet or microwave.
Assemble the Tacos: Layer cabbage or lettuce on each tortilla, top with shrimp, and spoon over generous helpings of mango salsa. Serve with lime wedges and enjoy!
