Shurpa is a hearty soup, it's filling and healthy. It reminds me of chili or beef stew; the flavors are right on and the combination of ingredients feel light on the stomach. The best part is that it reheats very well, so you can have it lasting for days.
For beef, you can pretty much use any cut. I would, however, recommend cuts with less fat, as they keep the soup on a lighter side.
