In a medium bowl, combine salmon cubes, 1/4 cup teriyaki sauce, olive oil, garlic powder, and ground ginger. Toss to coat evenly.
Preheat the air fryer to 400°F (200°C) for 3 minutes.
Arrange salmon cubes in a single layer in the air fryer basket, ensuring they do not overlap.
Air fry for 8 to 10 minutes, shaking the basket halfway through the cooking time, until the salmon is opaque and slightly charred.
Distribute cooked jasmine rice into two serving bowls.
Top rice with air-fried salmon bites, cucumber slices, and avocado.
Drizzle the remaining 1/4 cup of teriyaki sauce over the bowls.
Garnish with toasted sesame seeds and sliced green onions.
