Prepare the wooden skewers. I can get 7-8 large shrimps on a 1ft shish kebab skewer. Take out as many skewers as you need, and set them out in a tray of water for at least 20 minutes
Next, thaw and shell your shrimps. I recommend using large or jumbo size shrimps for this meal. Thaw the shrimp in a bowl of cold tap water for 20 minutes, then pull off the shell up to the tail and discard.
Add the olive oil, parsley, salt, pepper, lemon juice, lime juice, and minced garlic to a bowl and mix. Add the shrimp, cover the bowl, and gently shake to coat the shrimp with marinade. Let the shrimps marinate for 15 to 20 minutes.
Skewer the shrimp on the shish kebabs, and preheat your grill to 400F. Grill with the lid closed for 3-5 minutes, until the tops of the shrimp are white. Flip the shrimp and grill for 2-3 minutes more, until they have the amount of browning you desire.
