It's super simple, add everything but the avocado to a large bowl and combine!
Before serving, top with avocado.
Notes
Salad will last up to 1 week in a tight-sealed container in the fridge.The flavours will continue to build as time goes on. The longer, the better!If you don't have barley, substitute for any favourite grain or rice.If you don't have lentils, substitute for any favourite legume (chickpeas would be great).
