Brush 1 tbsp olive oil, lemon pepper, and salt onto fish fillets. Place in a skillet on medium heat and cook for approximately 8 minutes, until fish begins to flake.
While fish is cooking, combine green cabbage, daikon, carrots, cilantro, and jalapeno (optional) into a bowl.
In the mean time, place shredded cabbage into large broil pan and toss with remaining olive oil, remaining salt and lemon pepper.
Next mix together lime juice, cider vinegar, apple juice, mustard, and 2 tbsp olive oil. Mix well, and pour over cabbage mixture to make a slaw.
Place cooked fish on top of a corn tortilla, top with slaw. Can also add salsa in avocado** if you wish. Serve immediately.
