Use it like pearl barley too, lovely in a lamb casserole.
This is is a recipe straight off the top of my head. Everyone likes pea and ham soup, or lentil and ham. This (usually with split yellow lentils for me), is a standard camping meal. Easy, quick and filling.
Fry bacon or ham, add chopped onion, add a handful of buckwheat, add water, add a Knorr ham stock cube. Simmer, eat. Dip bread if you want.
Its versatile stuff and tasty.
