Start by cutting your skinless salmon fillets into bite-sized pieces. Season them with salt, black pepper, and cornstarch.
In a small bowl, combine soy sauce, honey, minced garlic, grated ginger (if using), and water. Whisk until smooth.
Preheat your air fryer to 400°F (200°C).
Toss the seasoned salmon pieces in olive oil and place them in the air fryer basket in a single layer. Air fry for about 8 minutes.
After 8 minutes, drizzle the honey garlic sauce over the salmon bites and toss to coat. Return to the air fryer for an additional 2 minutes.
Remove the salmon bites from the air fryer and garnish with sesame seeds and chopped green onions before serving.
