In a medium mixing bowl, add all the ingredients, except the chips, and mix well. Transfer to a 9 by 9-inch foil baking pan and cover with aluminum foil. Put on the grill over indirect heat (350 degrees F is ideal) and cook for 15 minutes, turning every 5 minutes, to keep the heat even. Carefully remove from the grill and serve with the chips.
The dip can be prepared in advance and kept in the refrigerator until ready to cook. If this is done, please add 10 minutes to the cook time.
