Perfect Bison Tenderloin

A couple of weeks ago, Neil put a whole bison tenderloin on the barbeque rotisserie. It was probably the best meat we've ever eaten in this house--and we've had some killer steaks. He applied my favourite flavouring (Mustard & Herb) to the 2 lb. tenderloin, then cooked it on the rotisserie for 1 hour and 15 minutes. Perfection!
