Set your George Foremen Grill to high.
Combine coffee, brown sugar, salt, cinnamon, ginger, black
pepper, cocoa powder and cardamom in a bowl.
Remove steak from refrigerator and let come to room
temperature, about 15 minutes. Rub steak with oil, and
sprinkle with rub. Massage rub into meat.
Grill until a light crust appears on the meat, and medium-rare, 4 to 7 minutes per side. Transfer to a cutting board, cover with foil and let rest 5 minutes before thinly slicing. Serve immediately.
