Nanbanzuke (Marinated Fried Fish)
When bite size pieces of deep fried fish are marinated in slightly sweet vinegar and soy based sauce with plenty of shredded vegetables, it transforms the fish into something totally different. It keeps well in the fridge and is usually served cold or at room temperature. Perfect in hot summer and for lunch boxes. Total Time does not include time to marinate.
