This a baked recipe however very delicious and easy

Mix together 1 small package of dry onion soup mix, 1 cup of ketchup, 1/2 cup brown sugar.

Pour mixture over chicken thighs, cover with tin foil and and bake at 350 degrees for an hour
Serve on top of rice

I suppose you could put it on the grill in a covered baking dish although I haven't tried it
