Mix spice rub ingredients in a small bowl. Have ready four 12-inch-long strips of heavy duty foil. Rub spice rub onto both sides of meat. Heat grill. Mix remaining ingredients in a bowl. Divide mixture among the 4 pieces of foil, placing mixture near one end. Fold in half to form packet; fold edges to seal completely. Grill packets 25-30 minutes, turning over once, until potatoes are tender when pierced. After packets have cookied 25 minutes (remove if done), add steak to grill. Grill 5-7 minutes per side for rare, 7-9 minutes for medium and 9-11 minutes for well done. Recipe by: Womens Day - 4/22/97 Posted to MC-Recipe Digest V1 #611 by The Taillons on May 13, 1997
