I broil my chicken breast with a mixture I've used for years - melted butter and lemon juice with a bit of salt and whatever herbs (dried) that I like. I start them out skin side down and when they are about half done turn them to finish broiling on skin side. I don't know how long it takes, I just look and see how they are doing and go from there. If I'm doing them on the grill I flipflop the procedure.
