As a person with a degree in Slavic Linguistics and a former resident of Moscow, I'll give you a nice "Russian" recipe. Not Soviet, not Siberian, just plain old Russian. It's called "Myaso po Derevinsky" or "Meat Village-Style". I make it occasionally to remind myself of the days in Russia.
1lb. Sirloin Steak, cut into bite-sized pieces
2-3 medium potatoes, sliced into medallions
1 green pepper, sliced
1 large onion, sliced
1/4 lb. shredded cheese (I use cheddar, but in Russia, it probably is something more like Feta... all I remember is that they called the cheese "horoshy" or "good" cheese"... not much of a name, admittedly but it was white and creamy like a good French Feta)
A pinch each of: dried oregano, coriander, thyme, basil and sweet paprika.
Mayo to slather on potatoes and meat.
Place meat into greased casserole. Season with above seasoning except paprika. Brush with mayo, add onion, peppers. Toss some grated cheese on top. Sprinkle with paprika. Stack potatoes on top, overlapping like roofing shingles. Brush with more mayo. Sprinke with rest of cheese, then paprika. Bake at 375 F or about 200 degrees celcius for about 30 minutes covered. Bake an additional 20 minutes or so uncovered until meat and potatoes are tender.
Sorry the recipe is so vague. A Russian friend taught it to me many moons ago when I lived in Moscow, so the measurements aren't exact. Good luck with your Russian friend.
