Scrub the potato and cut into thin fries or wedges, then toss with avocado oil and half of the salt and pepper.
Place potatoes in the air fryer at 400°F for 15-20 minutes, shaking halfway through until golden and crispy.
While potatoes cook, brown the ground turkey in a skillet over medium heat until fully cooked; remove and set aside.
In the same skillet, cook the bacon slice until crisp, then crumble into small pieces.
Prepare the high-protein ranch by whisking together the Greek yogurt, lemon juice, dill, garlic powder, and onion powder in a small bowl.
Arrange the crispy fries on a plate, top with the cooked ground turkey, crumbled bacon, and shredded cheddar cheese.
Place the plate under a broiler for 1 minute or back in the air fryer for 2 minutes to melt the cheese.
Drizzle with the prepared Greek yogurt ranch and serve immediately.
