Preheat your air fryer to 400°F (200°C).

Pat the salmon fillet dry with paper towels and brush it with olive oil.

In a small bowl, combine chili powder, cumin, garlic powder, salt, and pepper. Rub the seasoning mixture evenly over the salmon fillet.

Place the seasoned salmon in the air fryer basket and cook for about 10-12 minutes until it flakes easily with a fork.

In a large bowl, combine shredded cabbage, shredded carrots, and chopped cilantro.

Squeeze fresh lime juice over the mixture and toss to combine.

In another bowl, mix Greek yogurt or sour cream with lime zest.

Once the salmon is cooked, remove it from the air fryer and let it rest for a few minutes.

Warm the tortillas in the air fryer for about 2 minutes to make them pliable.

Flake the salmon into bite-sized pieces.

Place a few pieces of salmon on each tortilla, top with slaw, and drizzle with the yogurt or sour cream mixture.

Add avocado slices and salsa if desired. Serve immediately.
