Combine the chicken and the ranch dressing in a large bowl.

Lay the tortillas out on a counter or work surface.  (If the tortillas aren’t very pliable, heat in the microwave to soften so that they will roll without tearing.)

Divide the chicken mixture evenly between the 6 tortillas, placing it down the center of the tortilla.  Top with chopped bacon, shredded lettuce and diced tomatoes. Fold in the sides of the tortillas, then roll up.

Cut in half to serve.
