Ingredients for the marinated tofu
Cut tofu into the form you like.
In a tupperware box or a zip bag mix together the shoyu, rice wine vinegar, ginger- & garlic paste and brown sugar. Add the onions and put the tofu into the box. The tofu should be covered with the marinade. If not, you can add some water. Put the box into the refrigerator and let it rest over night or at least 8 hours.
Add oil in a medium heat frying pan and saute the tofu until golden brown.
