The traditional name for these comes from Polish,and they are now officially called "musti suktinukai", but the old name is still popular. This is a stuffed beef roll,a bit different from the more familiar German rouladen. Sandwich steaks are a great way to shortcut the prep. If you can get dried baravykai (porcini), the flavor is much enhanced, but don't worry about it if you cannot. Serve with mashed potatoes and a green veggie. Leftovers reheat and freeze very well.
