Rich, dark and delicious, mole is a signature sauce in mexican cooking. There are many variations, but the basic ingredients include plenty of chiles and nuts along with a touch of chocolate to tame the heat of the chiles. Traditional recipes can take several hours to prepare--this quick version takes a few shortcuts by using chili powder, nut butter and chocolate chips. Serve with rice and a medley of sautéed zucchini, pepper and onion.
