Variation: Potatoes can be cooked on the stove top instead of on the barbecue. Add whole Yukon gold and red potatoes to saucepan of boiling water; cook 25 to 30 min. or just until potatoes are tender. Meanwhile, cook cubed peeled sweet potatoes in separate saucepan of boiling water 15 to 20 min. or just until tender. Drain potatoes. Cut whole potatoes into 1-inch pieces, then prepare recipe as directed.
