Unlike the other recipies posted here, this one is almost real sukiyaki. Sukiyaki does not use green peppers or corn like the others try to tell you. You can use spinach if Napa cabbage is not available. The one change I recommend to make it authentic is to use cellophane noodles, not rice. A wok is nice, but a frying pan can work. Keep all veggies separated-none get mixed. A very impressive dish! Guests will be most impressed!
