Preheat the air fryer to 375°.
In a large bowl, toss the green beans with the oil and salt until evenly coated. Place in the basket of the air fryer and cook for 6 minutes.
While the green beans cook, get the salmon ready. Dry them off and place them on a plate. In a small bowl, combine garlic oil, lemon juice, and dill.
Once green beans have cooked for 6 minutes, remove them and top with the salmon pieces. Spoon the sauce evenly over each piece and sprinkle with the salt (1/4 teaspoon each). Make sure to have the rack over a plate so the extra sauce doesn't drip on the counter.
Place back in the air fryer and cook 6 minutes. Serve warm.
