In a medium bowl place shrimp, garlic, dill, and tarragon; toss to coat. Cut prosciutto slices in half lengthwise. Wrap each shrimp in a half-slice of prosciutto. Thread wrapped shrimp on skewers, leaving a little space between each piece. Spray lightly with cooking spray. Place skewers on center of cooking grate and grill for 5-6 minutes, turning once halfway through grilling time.
Yield: 12 servings
Note: If using wooden skewers, soak in water 30 minutes before using so ends won't burn during grilling.
