In a bowl, combine the shrimp, olive oil, garlic, chili powder, cumin, paprika, salt, pepper, and lime juice. Toss to coat the shrimp evenly and let marinate for 15 minutes.
Heat a large skillet over medium-high heat. Add the marinated shrimp and cook for 2-3 minutes per side until pink and cooked through. Remove shrimp from the skillet and set aside.
In the same skillet, add the red bell pepper, red onion, and jalapeno. Saute for 3-4 minutes until the vegetables are slightly softened.
Add the diced mango to the skillet and cook for another 2 minutes until the mango is heated through.
Warm the corn tortillas in a separate skillet or in the oven.
To assemble the tacos, place a spoonful of the mango and vegetable mixture on each tortilla, top with shrimp, and garnish with fresh cilantro.
Serve the spicy mango shrimp tacos with a dollop of sour cream and lime wedges on the side.
Enjoy these delicious tacos with a refreshing drink!
