Prep Shrimp: Ensure shrimp is shelled - you can leave the tail on if you want, personal preference.
Make Marinade: Add lime juice, lime zest, extra light olive oil, cilantro and kosher salt to a small food processor or blender. Blend until combined.
Marinate Shrimp: Place shrimp in a reusable silicone bag or glass bowl. Pour marinade over top and toss to coat. Cover and let marinate up to 30 minutes.
Grill Shrimp: Ensure grill grates are clean and grill is heated to medium-high heat (about 400-450 degrees F). Place shrimp/prawns over direct heat for 1-2 minutes per side or until shrimp are no longer opaque and cooked through (this might be less for smaller shrimp and more for thicker shrimp).
Stove Top Method: Add a tablespoon of olive oil (or ghee) to a large skillet (enough to coat) and bring to medium-high heat. Add shrimp/prawns to pan and cook about 2 minutes per side, or until fully cooked.
*Shrimp: make sure to fully thaw any frozen shrimp, remove the shells, and tails (if desired).
Storage: Store cooked shrimp in an airtight container in the refrigerator for up to 2-3 days.
