This is a simple recipe that I fixed last night on the grill.
Simple ingredients as the flavor of the quail is the main attraction.

4 quail
1/4 cup butter
1 tablespoon light vegetable oil
1/2 teaspoon salt
1/2 teaspoon coarse
1/4 teaspoon lemon juice
1/4 teaspoon garlic powder

Prepare the grill for medium high heat direct grilling. Lightly coat the quail with vegetable oil and lemon juice, then season with salt, pepper and garlic. Place the quail on the grill over direct heat, and cook 6-8 minutes per side. Move the birds to the cool side of the grill for 5 minutes to rest. As the quail are cooling, melt the butter. Split the quail along the breastbone, then brush with butter before serving.

Voila - And damn was it good
