My honey cut this out of one of his mags and taped it on the cabinet door for me to buy all the ingredients. After going to 3 different stores, I finally found all the stuff. This was worth the wait. Sorry, I have no pics. Trust me this is delicious.
Combine minced garlic, 1/2 cup rice vinegar, 2 T mirin(in international aisle), 2 T soy sauce, 1 T minced fresh ginger, 1 t wasabi powder, and salt and pepper. Brush chicken with oil and grill. Warm wasabi mixture and pour on the chicken, garnish with scallions and cilantro.
We served this on a bed of basmati rice and a side of broccoli.
notes: the is a little spicy
