Cook the bacon until crispy, then crumble into bite-sized pieces.
If needed, warm the tortillas briefly to make them more pliable.
In a mixing bowl, combine shredded chicken, crumbled bacon, shredded cheddar, ranch dressing, shredded lettuce, and diced tomato. Season with salt and pepper and stir until well blended.
Lay a warmed tortilla flat. Spoon a generous portion of the chicken mixture down the center.
Fold the sides of the tortilla over the filling, then roll up tightly to enclose everything.
Place the wrap seam-side down in a skillet over medium heat. Toast for 2–3 minutes on each side until golden brown and the cheese begins to melt.
Remove from the skillet, slice in half, and serve warm.
