In a small bowl, add ranch dressing, about 1 cup for six wraps, or to taste. Add cajun seasoning, stirring thoroughly and tasting, adding more to taste as necessary. I like to add a lot, enough to turn the ranch orange, but do a little at a time to make sure it suits your taste.
Lay out one wrap. Tear a piece of cheese in half and lay both halves in a line down the center of the wrap. Top the cheese with a handful of chicken, a few slices of tomato, and some lettuce. Drizzle the cajun ranch sauce over all.
Fold in the sides of the wrap, then roll it up tightly from the bottom like a burrito. Hold the wrap firmly, seam side down, and slice in half on a diagonal with a serrated knife. Serve with fresh fruit and vegetables, or chips and a pickle.
