15 mango pieces dried cut into 1/4- by 1-in. slivers
2 tbsp milk
30 mint leaves
1 tablespoon olive oil
Equipment
bowl
paper towels
knife
grill
Directions
Trim fat from steak. Rinse meat, pat dry, rub with oil, and sprinkle liberally with salt and pepper.
Lay steak on an oiled cooking grate over a solid bed of very hot coals or highest gas heat (you can hold your hand 1 to 2 in. above grate for only 1 to 2 seconds); cover gas grill. Cook until firm when pressed on thin end but still quite pink inside (cut to check), 8 to 10 minutes; turn over halfway through.
Transfer steak to a plate; let cool at least 30 minutes. About 45 minutes before slicing, put steak in the freezer (it will be easier to slice thinly).
On a board with a very sharp knife, cut steak across the grain, straight up and down and as thinly and evenly as possible, to make 30 to 34 slices; save narrow and uneven ends just to eat. If wet, blot with paper towels.
Measure accumulated meat juices and add enough milk to make 2 tbsp.; pour into a bowl. Crumble cheese into bowl and mash with a fork into a smooth paste.
Working with 1 steak strip at a time, lay strip on a flat side.
Spread strip with about 3/4 tsp. cheese mixture, then lay 1 mint leaf and 1 mango piece at end of strip and roll to enclose.
Let stand at room temperature at least 10 minutes before serving.
