1. 1. Prepare the Chicken Mixture: In a medium bowl, combine the shredded or diced cooked chicken with the Caesar dressing and grated Parmesan cheese. Stir well until the chicken is evenly coated. Season with a pinch of salt and black pepper to taste.

2. 2. Assemble the Wraps: Lay one tortilla flat on a clean surface. Spoon about 1/4 of the chicken mixture down the center of the tortilla, leaving space on the sides. Top the chicken mixture with about 1/2 cup of chopped romaine lettuce. If using, sprinkle some crispy fried onions or crushed croutons over the lettuce for added crunch.

3. 3. Fold the Tortillas: Fold in the sides of the tortilla over the filling, then tightly roll the tortilla from the bottom up, creating a secure wrap. Repeat with the remaining tortillas and filling.

4. 4. Heat the Skillet: Heat the olive oil or avocado oil in a large non-stick skillet over medium heat. You want the skillet to be hot enough to crisp the tortillas but not so hot that it burns them quickly.

5. 5. Crisp the Wraps: Carefully place the assembled wraps seam-side down into the hot skillet. Cook for 3-5 minutes per side, or until the tortilla is golden brown and crispy, and the filling is warmed through. You might need to gently press down on the wraps with a spatula to ensure even contact with the pan.

6. 6. Serve Immediately: Once crispy, remove the wraps from the skillet. You can slice them in half diagonally for easier eating and a more appealing presentation. Serve warm and enjoy your perfectly crispy chicken Caesar wraps!
