Toss chicken with mustard mixture; place in jelly-roll pan. Broil chicken, 5 to 7 inches from source of heat, 8 minutes. Remove pan from broiler, and sprinkle chicken with crumbs (do not turn chicken over). Return pan and broil 2 minutes longer or until crumbs are browned and juices run clear when thickest part of thigh is pierced with knife. Meanwhile, place unpeeled whole potatoes in microwave-safe large bowl; cover with vented plastic wrap. Microwave potatoes on High 5 minutes. Re-arrange potatoes and cook 5 minutes longer or until tender. Cool potatoes 5 minutes. Cut each potato lengthwise in half and scoop potato from skin into same bowl; discard skin. With potato masher, coarsely mash potatoes with margarine, 1/4 teaspoon salt, and 1/4 teaspoon ground black pepper.
