Fire up the grill and make these delicious homemade garlic shrimp skewers. The shrimp are marinated in a flavorful garlic and herb mixture, then threaded onto skewers and grilled to perfection. The smoky char from the grill adds an extra layer of flavor to the succulent shrimp. Serve these skewers as an appetizer at your next barbecue or as a main course with a side of grilled vegetables and a squeeze of fresh lemon.
