The goats cheese is optional, but I think it works as it makes a nice contrast to the earthy beetroot. Of course you could use a dairy free alternative like Gary which is actually made from coconuts and is very popular in the UK right now. I have to admit I have not tried Gary yet as every time I go to seek it out it is sold out.
This Beetroot Barley Goats Cheese Salad is not much of a recipe as I eye-balled most of the ingredients: cooked barley, cooked beetroot including its juices, a little balsamic vinegar an extra virgin oil for dressing, salt and pepper and then topped with rocket and goats cheese. Quite simple really.
