These are authentic Russian piroshki filled with ground beef and onion, seasoned with dill weed and deep fried. You could also add a little cheese in the filling as you are making them. They also may be baked.
This is a quick and easy recipe that never fails to please even my picky DDs. Since chicken thighs are usually inexpensive it makes a economical meal. I like to serve these with some type of rice side dish and a green salad.
