Marinated Grilled Shrimp

My friend Stefany taught us how to make these at our cooking group last month, don't they look yummy?

Marinated Grilled Shrimp

3 cloves garlic, minced
1/3 c. olive oil
1/4 c. tomato sauce
2 Tbs red wine vinegar
2 Tbs. chopped fresh basil
1/2 tsp salt
1/4 tsp cayenne pepper
2 lbs. fresh shrimp, medium sized, peeled and deveined
bamboo skewers

In a large bowl, stir together the garlic, olive oil, tomato sauce, and red wine vinegar. Season with basil, salt, and cayenne pepper. Add shrimp to bowl, and stir evenly to coat. Cover and refrigerate for 30 minutes to 1 hour, stirring once or twice. At this point add skewers to water to soak, this will prevent them burning up on the BBQ! They should soak for at least 1/2 hour.
Preheat grill to medium heat.
Thread shrimp on skewers, piercing once near the tail and once near the head. Discard marinade. Lightly spray grill with cooking spray. Cook shrimp for 2-3 minutes per side, until opaque and pink.
