These blackened fish tacos come together in under 30 minutes and make a delicious weeknight meal. Spiced white fish is folded into warm tortillas, topped with shredded red cabbage and drizzled with a creamy avocado sauce. You can make fish tacos with any firm white fish you prefer: tilapia, cod, mahi mahi, snapper, etc. I used Tilapia, it's inexpensive, easy to cook and light in
