Combine first 4 ingredients. Mix well and pour over shrimp in a large bowl. Allow shrimp to marinate for at least one hour. Prepare medium hot grill. Thread shrimp onto shish kabob-type skewers and grill for about 3 minutes per side over medium hot grill. If you do not want to grill the shrimp then broil them in the oven for about the same amount of time.
