This is a three cabbage slaw - green, red, and napa - but the real delight is the dressing. It is made with creamy peanut butter laced with brown sugar, fresh ginger, and garlic - and a bit of oil, vinegar, and soy sauce.
The delicate flavors of the fish are richly enhanced by the sweet tang of the wood planks. The mango salsa gives it a spicy flare. Just about any fish will work, I have used tilapia and it turns out well. This is great served with rice pilaf.
