01 - Combine shrimp with olive oil, chili powder, cumin, smoked paprika, garlic powder, salt, and pepper in a bowl. Toss until evenly coated and let marinate for 10 minutes at room temperature.
02 - Toss green cabbage, red cabbage, carrots, and cilantro in a large bowl. Whisk together mayonnaise, Greek yogurt, lime juice, honey, salt, and pepper in a small bowl. Pour dressing over vegetables and mix thoroughly. Refrigerate until ready to serve.
03 - Heat a large skillet over medium-high heat. Arrange shrimp in a single layer and cook for 2 to 3 minutes per side until pink and opaque throughout. Transfer to a plate and set aside.
04 - Warm tortillas in a dry skillet or microwave. Place a generous portion of slaw on each tortilla, top with cooked shrimp, and garnish with additional cilantro or jalapeños if desired. Serve immediately with lime wedges on the side.
