Slice the chicken breast into thin strips and place them in a bowl.
Toss the chicken with almond flour, sea salt, black pepper, and garlic powder until evenly coated.
Heat the avocado oil in a non-stick skillet over medium-high heat or preheat an air fryer to 400 degrees Fahrenheit.
Cook the chicken for 4-5 minutes per side in the skillet, or air fry for 10-12 minutes, until the coating is golden and crispy.
In a small bowl, whisk together the Greek yogurt, dried dill, onion powder, and lemon juice to create the clean ranch dressing.
Warm the tortilla slightly in a dry pan or microwave for 10 seconds to make it pliable.
Spread a layer of the yogurt ranch onto the center of the tortilla, then top with shredded romaine lettuce and diced tomatoes.
Place the crispy chicken strips on top of the vegetables, fold in the sides of the tortilla, and roll it tightly into a wrap.
