In a large bowl, combine the cooked chicken, crumbled bacon, shredded cheddar cheese, and ranch dressing. Mix well until everything is evenly coated. Add salt and pepper to taste.
If using, stir in the green onions and diced tomatoes.
Assemble the Roll-Ups:
Lay a tortilla flat on a clean surface.
Spread a quarter of the chicken mixture evenly over the tortilla, leaving a small border around the edges.
Roll the tortilla up tightly, starting from one end and rolling to the other.
Chill and Slice:
Place the rolled-up tortilla seam-side down on a plate.
Repeat the process with the remaining tortillas and chicken mixture.
Chill the roll-ups in the refrigerator for about 30 minutes to firm up (optional but helps with slicing).
Serve:
Slice each roll-up into 1-inch pieces.
Arrange the pieces on a serving platter.
Tips:
These roll-ups can be made a few hours ahead of time and stored in the refrigerator until ready to serve.
For a healthier option, use whole wheat tortillas and turkey bacon.
Feel free to add other favorite ingredients such as avocado, bell peppers, or cucumbers.
