Preheat the air fryer to 400°F.
In a bowl, toss the cubed salmon with avocado oil, chili powder, salt, garlic powder, and black pepper until evenly coated.
Arrange the salmon cubes in a single layer on the air fryer tray.
Air fry for 6 to 8 minutes until the salmon is cooked through and slightly crispy on the edges.
While the salmon cooks, melt the butter in a pan over medium heat and sauté the minced garlic until golden and fragrant. Remove from the heat.
Stir in the honey and lemon juice, letting the sauce simmer for about a minute until slightly thickened.
Once the salmon is done, toss it in the honey lemon garlic sauce until fully coated.
Serve immediately and enjoy!
