Prepare the meat per this link.
However, do not slice into steaks. Instead, leave as one large single piece of meat.
Take meat from Sous Vide cooker, then place into very hot oven (e.g., 450 dF) or hot grill (with lid on grill).
Cook until brown. If on grill, you may need to turn.
Since the meat is already cooked and you are just browning the meat, watch for it to take on the amount of toasting you desire.
Serve on platter, slicing with long, thin knife to serve directly to plates.
