Step 1: Miso Butter ... Add the butter, miso, chicken broth, chilies, lime zest, a pinch of salt and pepper, to a food processor; and, puree until smooth. Transfer to a small bowl, cover; and, refrigerate until ready to use. It will develop more flavor as it sets - at least 4-6 hours; or overnight if possible. But, before using it; I like to bring it to room temperature, softened.
Step 2: NOTE: If you don't like heat or spice ... remove the seeds and ribs from the peppers; personally, it really isn't too hot. I recommend a small or even half of a jalapeno, for those who don't like too much heat.
Step 3: Vegetables ... You can use a food processor, box grater; or, chop by hand; that is up to you. Honestly, I use the box grater for the carrots and cabbage; and hand chop the water chestnuts, mushrooms, and scallions. Once everything is prepped, transfer the cabbage, carrots, water chestnuts, lime juice, sesame oil, salt and pepper to a bowl; and toss to combine;. Transfer the mushrooms and scallions to a smaller bowl on the side.
Step 4: Rice ... Now, if you are serving this with rice - start it now. It will take approximately the same time as the fish.
Step 5: Fish Packets ... Use a nice size sheet of foil; approximately 12x18" (for each fish fillet), that will be plenty of room for the fish and vegetables. Spray the center of the foil with a non-stick spray (you can also brush it with a little vegetable oil). Then, add 1/4 of the cabbage mix to each foil sheet; and top with the fish. Season the fish with salt and pepper; then, slather the fish with 1/4 of the miso butter over the top. Top that with 1/4 of the mushroom/scallion mix - and, don't worry if some fall off the top. Fold up the foil to make a pouch. Make sure the pouch is sealed well.
Step 6: Note: I know 2 tablespoons of butter sounds like a lot; but, it really is the sauce for the fish, vegetables, and rice. And, if you don't have to use it all if you don't want too. But, it is worth it.
Step 7: Bake ... Place the pouches on a heated baking sheet; and, bake at 375 - for approximately 25 minutes (for salmon); 15-18 for tilapia, 25 for halibut; and 30 for cod. Obviously, the thicker the fish; the longer it takes. I hate to say it; but, you just have to check. Also, when the foil PUFFS up, that usually means the fish is done. To heat the baking sheet; simply add the sheet to the oven when you preheat it.
Step 8: Serve, Plate, and ENJOY! ... Now, to serve - simply add the foil pouch to each plate; add a scoop of rice if you want, right in the pouch next to the fish - which I do. Then, garnish with a little unagi or soy sauce and sesame seeds. I always put the sauce on the table for those who want to add it.
