In a bowl, combine the shrimp, minced garlic, olive oil, chili powder, smoked paprika, cayenne pepper, lime juice, salt, and pepper. Mix well to coat the shrimp evenly. Let marinate for 15-20 minutes.
Heat a large skillet over medium-high heat. Add the marinated shrimp, cooking for about 2-3 minutes on each side until they turn pink and opaque. Remove from heat.
In a separate skillet, lightly warm the corn tortillas over medium heat for about 30 seconds on each side until pliable.
On each tortilla, layer a small handful of shredded red cabbage, a few shrimp, and slices of avocado.
Top each taco with fresh cilantro leaves and serve with lime wedges on the side for an extra zesty kick.
Notes
Adjust the cayenne pepper to taste for desired spiciness.
