Combine all dipping sauce ingredients in a bowl. Mix with a fork and crush the avocado so it's a creamy mixture. Can be made up to three days in advance.
Cilantro Lime Shrimp
Preheat the grill and set up for direct grilling targeting 400 - 450 degrees in the cooking chamber. While grill warms up, marinate the shrimp and soak wooden skewers in water.
In a large bowl combine the marinade ingredients and stir to incorporate. Add the shrimp and stir. Marinate for 15 - 20 minutes. Occasionally stirring the shrimp.
Place shrimp on the skewer. We use smaller skewers with four shrimp to a skewer. Place shrimp on the grill over direct heat. Grill for 4 - 5 minutes on one side or until you see nice grill marks. Flip the shrimp and continue grilling until they look pink or they read at least 135 degrees F on an instant read thermometer. About 3 - 4 additional minutes.
