How do you slice a flat iron steak?

1. Let the flat iron steak rest for about 10 minutes before slicing this will allow the juices to redistribute for even slices.

2. Locate the grain of the meat. To do this look closely and you'll see that the muscle fibers will appear to be running in parallel lines in one orientation.

3. Slice. Now all you have to do is cut across those muscle fibers!
