In a bowl, combine the shredded chicken with ranch dressing. Mix well until the chicken is fully coated.
Lay out the flour tortillas on a clean surface.
Evenly distribute the chicken mixture among the tortillas, placing it slightly off-center.
Top the chicken with shredded lettuce, diced tomatoes, cheddar cheese, and chopped corn chips for crunch.
Season with salt and pepper according to your taste.
Fold in the sides of the tortilla and then roll it up tightly from the bottom to the top.
Heat olive oil in a skillet over medium heat. Place the wraps seam-side down in the skillet and cook for 3-4 minutes per side, or until they are golden brown and crispy.
Remove the wraps from the skillet and let them cool for a minute before slicing them in half.
Garnish with fresh dill if desired and serve with extra ranch dressing for dipping.
