Preheat oven to 425° F and line a baking sheet with parchment paper or foil. Pat dry the fish filets with paper towels to remove as much moisture as possible. Drizzle the fish with the olive oil on all sides.
Combine the fish seasoning blend and sprinkle all over the fish on all sides. Place fish on prepared baking sheet and bake for 12 to 15 minutes, until fish flakes easily at thickest point. Temperature of fish should reach 140 degrees F.
Break fish apart and serve in warm corn tortillas with toppings and a squeeze of lime juice on top. Enjoy!
