In a large mixing bowl, combine shredded chicken, cream cheese, cheddar cheese, crumbled bacon, ranch seasoning mix, and milk. Mix until smooth and creamy.

Lay a flavored tortilla flat on a clean surface and spread approximately ⅓ of the chicken mixture evenly across it, leaving a border.

Starting from one edge, roll the tortilla tightly, tucking the filling inside, and secure the seam side down.

Wrap each pinwheel tightly in plastic wrap and refrigerate for at least 2 hours or overnight.

Carefully remove plastic wrap and slice the rolls into ½-inch thick pinwheels. Serve with your favorite dip.
