Kreplach are often made for the Purim feast. They are dumplings filled with meat, onions, and spices. They can be served in chicken soup (similar to won ton soup) or fried and served as a side dish. This recipe is for ground beef kreplach but you could also use chicken or other vegetables to make a vegetarian version. If you prefer, you may leave the cinnamon and walnuts out of this recipe.
