Combine water and vinegar and use to wash chicken breasts. Drain and pat dry with paper towel.
Flatten each chicken breast with a mallet and then set aside.
Combine mirin, sake, soy sauce, dark sugar, grated ginger and minced garlic in a bowl and mix well to dissolve the sugar granules and blend the flavours.
Pour the mixture over the flattened chicken breasts, cover and allow to marinate in the refrigerator for 2 hours.
Heat Grace Vegetable Oil in a skillet, add the drained chicken breast and brown on both sides.
Add the marinade to the browned chicken and bring to a boil. Allow sauce to reduce for about 10-15 minutes or until the mixture becomes glossy and lightly thickened.
Remove from skillet, slice and serve.
Serve with boiled rice or rice & peas and sauteed vegetables.
