Preheat your air fryer to 400°F (200°C) for at least 5 minutes.

Pat the salmon fillet completely dry with paper towels. Cut into 1-inch to 1.5-inch uniform cubes.

In a medium bowl, whisk together the avocado oil, low-sodium soy sauce, honey, garlic powder, smoked paprika, and black pepper until smooth.

Add the salmon cubes to the marinade and gently toss to coat every piece evenly.

Arrange the salmon bites in a single layer in the preheated air fryer basket. Ensure there is space between each piece and do not overcrowd.

Air fry for 8-10 minutes, shaking the basket gently halfway through (at the 4-5 minute mark).

The salmon is done when it's opaque, flakes easily, and the edges are caramelized. The internal temperature should be 125-130°F.

Carefully remove from the air fryer, garnish with sesame seeds and green onions if desired, and serve immediately.
