In a medium bowl, combine the shredded chicken and buffalo sauce. Mix well until the chicken is evenly coated.
Lay out the flour tortillas on a clean surface.
Divide the buffalo chicken mixture evenly among the tortillas, placing it in the center of each.
Top the chicken with chopped romaine lettuce, cherry tomatoes, and shredded cheddar cheese.
Drizzle ranch dressing over the toppings and season with salt and pepper to taste.
Fold in the sides of each tortilla, then roll from the bottom up to enclose the filling.
If desired, grill the wraps in a skillet over medium heat for 2-3 minutes on each side until golden brown and heated through.
Slice each wrap in half and serve immediately.
