We're grillin flat-iron today, medium-rare, with a smoke chip box to give it some mesquite flavor.
Grill it slow, on the cooler side of the grill, after first searing your grill marks in on the hot side.
It can take 30-40 minutes if done just right.
The searing locks in the juices, and keeps the meat moist as it cooks.
MMMMMMMMM good.
