Preheat the oven to 425°F (or 375°F if your oven typically runs hot).
Brown the ground chicken in a skillet for 10-15 minutes, until the moisture has evaporated off of the meat. Once cooked through, add the taco seasoning and lime juice and stir.
Wrap the tortillas in a towel and microwave on high for 60 seconds. Then, lay the tortillas out on a sheet pan and spray or brush 1 side of the tortillas with olive oil. Flip the tortillas so the olive oil side is down.
Sprinkle 1 tablespoon of cheese on half of each tortilla. Top the cheese with 2 tablespoons of the ground chicken mixture.
Add another tablespoon of cheese on top of the ground chicken mixture.
Place the tacos in the oven (open) to bake at 425°F for 5 minutes, then pull the tacos out, fold them over, and put them back in the oven to finish baking for 15 minutes.
While the tacos are baking, make the ranch-style sauce by adding the mayonnaise, dill, and lemon juice to a bowl and whisking until smooth.
Garnish the tacos with chopped onion, tomato, and cilantro, and serve alongside the ranch dipping sauce. Enjoy!
