Toss shrimp in pesto, allow to marinate for 15 minutes.
Thread shrimp onto skewers. Grill over medium-high heat for 1-2 minutes per side. Shrimp cooks VERY quickly, remove from grill just as it is starting to turn pink.
Notes
Serves 4 as an appetizer, 2 for a main meal. Depending on the size of your shrimp, 1 pound will be about 18 shrimp.
