Marinate the Shrimp: In a medium bowl, combine olive oil, lime juice, minced chipotle peppers, smoked paprika, garlic powder, cumin, salt, and pepper. Add shrimp and toss to coat evenly. Let marinate for 10–15 minutes.
Prepare the Creamy Drizzle: In a small bowl, mix sour cream, lime juice, chipotle powder or adobo sauce, and a pinch of salt. Set aside.
Cook the Shrimp: Heat a skillet over medium-high heat. Add shrimp in a single layer and cook 2–3 minutes per side until pink and opaque. Remove from heat.
Warm the Tortillas: Warm tortillas in a dry skillet, oven, or microwave until pliable.
Assemble the Tacos: Place shrimp on tortillas. Top with shredded cabbage, diced red onion, avocado slices, and chopped cilantro. Drizzle with the creamy lime-chipotle sauce.
Serve: Serve immediately with lime wedges on the side for extra brightness.
