Start by shredding the cooked chicken into bite-sized pieces.
In a large bowl, mix the shredded chicken with buffalo sauce until fully coated.
Lay a flour tortilla flat on a clean surface.
Spread a tablespoon of ranch dressing onto the tortilla.
Place a handful of shredded lettuce in the center of the tortilla.
Add a few diced tomatoes on top of the lettuce.
Spoon a generous portion of the buffalo chicken mixture onto the veggies.
Sprinkle shredded cheese over the chicken.
Fold in the sides of the tortilla, then roll it tightly from the bottom up.
Slice the wrap in half diagonally and serve.
