Begin by cooking your chicken if you haven’t done so already. You can use leftovers or a rotisserie chicken for convenience. Chop the cooked chicken into bite-sized pieces and set aside.

In a skillet over medium heat, cook the bacon until crispy, which should take about 5-7 minutes. Once cooked, remove the bacon, let it cool slightly, then crumble it.

In a large mixing bowl, combine the chopped chicken and crumbled bacon. Pour in the ranch dressing, mixing until all ingredients are well-coated.

Taste your filling mixture and sprinkle in salt and pepper to enhance the flavor.

Grab your hoagie or sub rolls and slice them open lengthwise, ensuring not to cut all the way through.

Generously spoon the chicken and bacon mixture into each roll, packing it in well.

Top each filled roll with shredded lettuce and diced tomato.

Finish by sprinkling shredded cheddar cheese on top.

Serve your sandwiches right away while they're still warm.
