Slice tofu into about 6 slices. Grate potato and onion into a dish. Add flour,parsley and seasonings to the potato mixture. Coat tofu slices with the potato mixture, pressing it in with your hands so it sticks well. Refrigerate for at least 1/2 hour which kind of sets it. Put enough olive oil into a skillet to cover bottom (and then some). Let it get good and hot. Saute slices until crispy and brown on each side. Serve with apple sauce or non-dairy sour cream or both. Its also fantastic dipped into a little wasabi!!!
