Quick Barbecue Chicken

I came across this recipe in my Cooking Light magazine and it looked pretty easy so we gave it a try. It was really good!

1 teaspoon sugar
1 teaspoon chili powder
2 teaspoons olive oil
1/2 teaspoon salt
1/4 teaspoon garlic powder
1/4 teaspoon ground cumin
1/8 teaspoon ground ginger
1/8 teaspoon ground cinnamon
1/8 teaspoon freshly ground black pepper
2 (8-ounce) bone-in chicken breast halves
Cooking spray

Prepare grill. Combine first 9 ingredients in a bowl, stirring well. Loosen skin from chicken by inserting fingers, gently pushing between skin and meat; rub spice mixture evenly under skin over meat. Lightly coat skin with cooking spray. Place chicken, breast-side down, on a grill rack coated with cooking spray; grill 30 minutes or until a thermometer inserted in the thickest part registers 165°, turning twice. Let chicken stand 10 minutes. Remove skin; discard.
