This is a recipe my mom used to make, and the family has always enjoyed it. Perhaps "Southern" in style, but technically, it's a Russian dish. I won't vouch for how Russian my version is though! It's easy to make in whatever amount you choose, and ingredient amounts are flexible as well. Any steak sort will work, including cheaper round steak. Some like it with a little onion, though we prefer it without. If you want that, perhaps a half cup finely chopped and added with the mushrooms, or just a dash or two of onion powder, if you prefer. Nice and filling dish, great for cooler nights.
