Greg's Pinwheel Flank Steak...Source: Greg Mixson

Flank steak
Spinach
Feta cheese
Finely chopped red/green peppers
Salt/pepper/JGM mix See recipe

Trim a fairly large piece of flank steak of excess fat.  
Place the steak between two layers of plastic wrap, and 
flatten with a meat hammer, working from the inside of the 
steak, out. (An empty wine bottle as a good hammer also, 
just be careful not to pound too hard).  
Once the steak is flattened to about 1/2 inch thick, season 
with salt, pepper, and JGM mix.  
Then cover the steak with a layer each of fresh spinach, 
feta cheese, and finely chopped red pepper. Roll into a "log". 
Cut the log into 1-2 inch thick steaks, holding them together 
with toothpicks and/or skewers. 
Grill until done as desired, about 5-10 min per side on hot grill.
