Prep the salmon. Cut the salmon into evenly sized cubes, about 1-inch each. Pat the salmon cubes dry with paper towels.
Season the salmon. In a bowl, whisk together olive oil, lemon zest, garlic powder, Aleppo pepper, smoked paprika, salt, and pepper. Gently toss the salmon cubes in the mixture until evenly coated. Set aside.
Air fry the salmon. Preheat your air fryer to 400°F. Arrange the salmon cubes in a single layer in the basket, leaving some space between pieces. Air fry for 5 minutes, then gently flip the cubes or shake the basket. Cook another 3 to 5 minutes, until the salmon is just cooked and edges are nicely browned.
Make the Honey-Harissa Glaze (optional). While the salmon cooks, make the glaze. In a small sauce pan, warm the honey, harissa, and garlic together over medium-low heat, just until runny. Remove from heat. Add a pinch of salt and the lemon juice, stirring until combined.
Finish and serve. Remove the salmon from the air fryer. If using the glaze, transfer the salmon bites to a large bowl, drizzle with the glaze, and gently toss to coat. Transfer to a serving platter, and scatter with fresh chives.
