I recently made and enjoyed this
Mediterranean Barley Salad. It can be eaten cold, but I do like it heated a little bit. I added black beans and feta cheese. Others have added chick peas or chicken for added protein. I've found barley to be incredibly filling, like holy cow I feel like my tummy will explode type filling!
I usually do the same as Munchy and make a big batch of something to eat all week or freeze.
