Preheat grill to medium.
Pat shrimp dry with paper towels, and place on bamboo skewers.
Brush shrimp with 1/4 cup dressing, sprinkle with a generous amount of salt and pepper and place on the grill.
Grill 2 to 3 minutes per side, or until shrimp are opaque and cooked through. Baste once, if desired.
In a small bowl, combine mayonnaise with remaining 1 tablespoon of roasted garlic dressing, 1 teaspoon minced garlic, and 1 teaspoon paprika. Serve as a dip for the shrimp.
