In a large bowl, combine the coleslaw mix, diced jalapeños, red onion, and chopped cilantro. Mix well.
In a separate bowl, whisk together the mayonnaise, sour cream, and 2 tablespoons of lime juice. Pour this mixture over the slaw and toss until coated. Chill.
Toss the shrimp with Cajun seasoning, remaining lime juice, and minced garlic in another bowl until well coated.
Heat olive oil in a skillet over medium-high heat. Add shrimp and cook for 2-3 minutes per side until pink and cooked through.
Warm the flour tortillas in a skillet or microwave until pliable.
Assemble tacos with creamy slaw and Cajun shrimp. Garnish with extra cilantro or lime juice, if desired.
Notes
Let shrimp marinate in Cajun seasoning for extra flavor. Use corn tortillas for a gluten-free option.
