I made this fab tempeh ruben with my homemade rye bread. I've never had a real ruben so I have nothing to compare this to, but it was delish. I got the recipe from somewhere in vegan-blogland. The tempeh is pan-fried with some tamari, and the sauce is Veganaise, chopped pickle and a touch of ketchup. I really am going to make my own sauerkraut soon - it seems so easy!
