Combine the brown sugar, paprika, onion powder, salt and chili powder and rub all over the chicken.
Moisten a paper towel with cooking oil. Using long-handled tongs, lightly coat the grill rack with the oil.
Grill the chicken thighs, covered, over medium heat for 5 to 7 minutes on each side, until opaque and cooked through or until a thermometer reads 170°F.
If you don't have a thermometer, to test for doneness, pierce a thigh with a knife and, if the juice is clear, the thighs are done.
Notes
Serving size: 1 chicken thighWW Points: 1Check your WW Points for this recipe and track it in the WW app. (Must be logged into WW on a smartphone or tablet.)5PointsPlus (Old plan)The only change I made was to use boneless skinless chicken thighs instead of breasts. I think they are more flavorful. And the thighs stay moist and tender, even if left on the grill a little too long. While the chicken cooks, you can grill some vegetables or toss together a simple salad.
