Slice the chicken breast into thin strips and pat dry with a paper towel.
In a small bowl, whisk together the almond flour, half of the garlic powder, half of the onion powder, sea salt, and black pepper.
Dredge the chicken strips in the almond flour mixture until lightly coated.
Heat the avocado oil in a non-stick skillet over medium-high heat or preheat an air fryer to 400°F.
Cook the chicken for 4-5 minutes per side in the skillet, or 8-10 minutes in the air fryer, until golden brown and cooked through.
While the chicken cooks, prepare the ranch dressing by mixing the Greek yogurt, dried dill, remaining garlic powder, and remaining onion powder in a small dish.
Warm the tortillas in a dry pan for 30 seconds until pliable.
Assemble the wraps by spreading the yogurt ranch onto each tortilla, then layering with shredded romaine, diced tomatoes, and the crispy chicken strips.
Roll tightly and serve immediately.
