Step 1: Prepare the Blackening Seasoning: In a small bowl, mix paprika, garlic powder, onion powder, thyme, oregano, cayenne, salt, and black pepper. Pat salmon dry with a paper towel and rub the spice mixture evenly over both sides.
Step 2: Make the Cilantro Lime Slaw: In a medium bowl, combine shredded cabbage, chopped cilantro, lime juice, and olive oil (or mayonnaise). Season with salt and black pepper. Toss well and set aside.
Step 3: Cook the Salmon: Heat olive oil or butter in a nonstick skillet over medium-high heat. Add salmon and sear for 3–4 minutes per side, until blackened on the outside and cooked through. Remove from heat and let rest for 2 minutes, then flake into bite-sized pieces.
Step 4: Warm the Tortillas: Heat tortillas in a dry skillet, oven, or microwave until warm and pliable.
Step 5: Assemble the Tacos: Place flaked salmon on each tortilla. Top with cilantro lime slaw and optional avocado slices, pickled onions, or jalapeños. Serve immediately with lime wedges.
