01 - In a medium bowl, toss the shrimp with olive oil, chili powder, smoked paprika, cumin, garlic powder, cayenne, salt, and black pepper until evenly coated. Set aside to marinate briefly.
02 - In a large bowl, combine the shredded green and purple cabbage, julienned carrot, and chopped cilantro. In a separate small bowl, whisk together the mayonnaise, Greek yogurt, minced garlic, lime juice, lime zest, honey, and salt until smooth. Pour the dressing over the cabbage mixture and toss thoroughly to coat. Refrigerate until ready to serve.
03 - Heat a large skillet over medium-high heat. Arrange the seasoned shrimp in a single layer and cook for 2 minutes per side until pink, opaque, and lightly charred. Remove from heat immediately.
04 - Warm the tortillas in a dry skillet or directly over an open flame for about 30 seconds per side until pliable and lightly toasted.
05 - Place a generous scoop of garlic cilantro lime slaw onto each warm tortilla. Top with the spicy shrimp, then garnish with fresh cilantro and a squeeze of lime juice.
06 - Serve the tacos immediately while the shrimp are still warm and the tortillas are soft.
