Creating Grilled Shrimp Tacos is a delightful process. Follow these simple steps to ensure success:

1. Marinate the Shrimp: In a bowl, combine olive oil, minced garlic, chili powder, cumin, smoked paprika, salt, pepper, and lime juice. Add shrimp and toss to coat. Let marinate for 10-15 minutes.
2. Preheat the Grill: Heat a grill to medium-high heat. If using a grill pan, preheat over medium heat.
3. Grill the Shrimp: Thread marinated shrimp onto skewers if desired. Place them on the grill and cook for about 2-3 minutes per side or until opaque and slightly charred.
4. Warm the Tortillas: Place tortillas on the grill for about 30 seconds per side until warmed through. Alternatively, they can be wrapped in foil and warmed in the oven.
5. Assemble the Tacos: Place grilled shrimp in the center of each tortilla. Top with shredded cabbage, diced tomatoes, chopped cilantro, and avocado slices.
6. Serve: Serve immediately with lime wedges on the side for squeezing over the tacos.

These straightforward steps will guide you in creating a flavorful grilled shrimp taco experience that is sure to impress everyone at your table.
