Tips for Perfect Shrimp

• Dry shrimp before seasoning for better browning.

• Don’t marinate longer than 20 minutes because the lime juice can start to “cook” the shrimp.
• Grill over high heat for a smoky char.
• Chill the lettuce leaves beforehand for extra crispness.

Frequently Asked Questions (Q&A)

Q: Can I use frozen shrimp?

A: Yes. Thaw completely, drain well, and pat dry before seasoning.

Q: Can I cook the shrimp without a grill?

A: Absolutely. Use a grill pan, cast-iron skillet, or air fryer at 400°F (200°C) for 6–8 minutes, flipping halfway.

Q: How spicy is this recipe?

A: It’s mildly spicy. Omit the cayenne and use a mild Cajun seasoning for less heat.

Q: Can I make the avocado sauce ahead?

A: Yes. Prepare it up to one day ahead and store it in an airtight container with plastic wrap pressed directly onto the surface.

Q: What lettuce works best?

A: Butter lettuce offers soft, cup-shaped leaves, while romaine provides a crisp, sturdy crunch.

Q: Can I use chicken instead of shrimp?

A: Yes. Grilled Cajun chicken breast or thighs make an excellent substitute.

Q: Is this recipe keto-friendly?

A: Yes. It’s naturally low in carbohydrates and fits well into a keto or low-carb eating plan.

Q: Can I meal prep these wraps?

A: Yes. Store the shrimp, vegetables, lettuce, and sauce separately, then assemble just before eating for the freshest texture.

Q: How do I know when shrimp are done?

A: Shrimp are cooked when they turn pink, opaque, and curl into a loose “C” shape. Overcooked shrimp become firm and tightly curled.

Q: What can I use instead of Greek yogurt?

A: Sour cream works well, or use a dairy-free plain yogurt if you need a dairy-free option.
