Preheat your air fryer to 400°F and cube the sweet potato into small, uniform bite-sized pieces.
Toss the sweet potato cubes with 0.5 tsp of avocado oil and a pinch of the sea salt, then air fry for 12 minutes until tender and slightly browned.
Slice the chicken breast into even strips and place them in a bowl, coating thoroughly with the plain Greek yogurt.
In a separate shallow dish, whisk together the almond flour, nutritional yeast, garlic powder, onion powder, smoked paprika, remaining sea salt, and black pepper.
Dredge each piece of yogurt-coated chicken in the almond flour mixture, pressing firmly to ensure the crust adheres to all sides.
Lightly spray the breaded chicken with the remaining avocado oil and air fry at 375°F for 10-12 minutes, flipping halfway through, until golden and crispy.
While the chicken finishes, steam the green beans for 4-5 minutes until they are bright green and crisp-tender.
Arrange the crispy chicken strips on a plate alongside the roasted sweet potatoes and steamed green beans for a balanced, clean feast.
