In a
bowl, stir together the garlic, mustard, and lime juice.
Trim the steak if necessary. Rub steak with mustard mixture
and marinate 15 minutes. Heat a well-seasoned ridged grill
pan over moderately high heat until just smoking and grill
steak 3 minutes on each side. (Alternatively, broil steak
on the rack of a broiler pan about 4 inches from heat.)
Transfer steak to a platter and let stand, uncovered, 5
minutes.
With
a sharp knife, diagonally cut the steak across the grain
into 1/3-inch-thick slices and serve with coleslaw and fries.
