Creating Grilled Shrimp Tacos with Lime Crema is straightforward if you follow these steps:

1. Marinate the Shrimp: In a bowl, combine olive oil, chili powder, cumin, garlic powder, salt, and pepper. Add shrimp and toss to coat. Let it marinate for about 10 minutes.
2. Prepare the Lime Crema: In a separate bowl, whisk together sour cream, mayonnaise, lime juice, lime zest, and a pinch of salt until smooth. Adjust seasonings if needed.
3. Preheat the Grill: Heat your grill over medium-high heat. If using a grill pan, preheat it on the stove.
4. Grill the Shrimp: Place the marinated shrimp on the grill. Cook for 2-3 minutes on each side or until shrimp are opaque and cooked through.
5. Warm the Tortillas: While the shrimp is grilling, warm the corn tortillas on the grill or in a skillet for about 30 seconds on each side until pliable.
6. Assemble the Tacos: On each tortilla, layer shredded cabbage, grilled shrimp, and slices of avocado.
7. Drizzle with Lime Crema: Generously drizzle lime crema over the top of the tacos.
8. Garnish: Add fresh cilantro and squeeze lime wedges over the tacos for an extra zing.
9. Serve Immediately: Enjoy your deliciously fresh Grilled Shrimp Tacos with Lime Crema while they’re still warm!
