Place a 14-inch camp Dutch oven over a pile of hot charcoal. Add all of the butter and half of the olive oil. When the butter is melted and the oil is hot, place the chicken tenders into the bottom of the oven, leaving lots of space between each piece. Fry the chicken for about 2 minutes or until it is golden brown, then turn. Remove the chicken when both sides are golden brown and crispy. Place on a dry paper towel.
