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 cabbages, julienned carrot, and chopped cilantro. In a small bowl, whisk together the mayonnaise, Greek yogurt, minced garlic, lime juice and zest, honey, and salt until smooth. Pour the dressing over the slaw and toss thoroughly to combine. Refrigerate until ready to use.
03 - Heat a large skillet over medium-high heat. Arrange the seasoned shrimp in a single layer and cook for 2 minutes per side, or until they turn pink and become opaque throughout. Remove from heat immediately to prevent overcooking.
04 - Warm the tortillas in a dry skillet or directly over an open flame for about 30 seconds per side until pliable and lightly charred.
05 - Place a generous scoop of garlic cilantro lime slaw onto each warm tortilla. Top with the spicy shrimp and garnish with extra cilantro and a squeeze of fresh lime juice.
06 - Serve the tacos immediately while the shrimp are still warm and the tortillas are pliable.
