Preheat the oven to 425°F, melt butter, and mix the seasoning.
Dip fish fillet into butter first and let excess butter drip off. Then, dip fish into the seasoning and flip it around to coat the fillet on all sides.
Place an empty skillet into the preheated oven let it heat through for a few minutes. Take it out, pour in some melted butter and add seasoned fish fillet. Bake fish for 13-15 minutes, depending on the thickness.
Slaw:
Slice cabbage as thinly as you can and combine it with vinegar, lime juice, and sugar. Mix well and let it sit until ready to use.
Mango Salsa:
Cut mango and combine it with diced red onion, diced jalapeno, cilantro, and lime juice. Mix well and set aside until ready to top tacos.
Prepare Tacos:
When fish is ready, take it out of the oven and let it sit on a cutting board for about 5 minutes.
In a mean time, spread out tortillas on a baking sheet and pop it into the oven to heat up.
To make tacos, add some slaw in the middle of each tortilla. Flake off chunks of fish and divide it among the tortillas. Scoop a couple of tablespoons of mango salsa on top of fish and enjoy.
Notes
How to tell if fish is done: Baking time of the fish will depend on the type of fish, thickness of fillet, and size of fillets. Always check for doneness at the thickest part. You can touch it with your finger and press down gently to see how firm the flesh feels. You can also use a fork to flake off some of the meat to make sure it's completely opaque inside. Proper temperature for the fish when it's done is 145°F. Some people prefer fish at about medium-well doneness because it more juicy. Medium well for fish is about 135°F.
