Bring the water to boil and add the sliced tofu. Wait until the tofu slices rise to the water's surface and remove from the pan. Blot dry. Mix the miso with the mirin and water until smooth. Combine the miso with the other marinade ingredients and pour the marinade over the tofu. Leave for about 20 minutes to allow the flavour to soak into the tofu.
Remove from the marinade, and sprinkle oatmeal over each slice
Heat the oil in a non stick pan and cook the cutlets over a low heat for 3 - 4 minutes each side. Serve with stir fried greens or creamed spinach.
Note : Flours, oatmeal and other grains will stay fresh and free of weevil infestation if stored in the fridge or freezer.
