Prepare the Filling: In a large bowl, combine shredded chicken, crumbled bacon, ranch dressing, and shredded cheddar cheese. Mix well and season with salt and pepper to taste.
Assemble the Egg Rolls: Lay an egg roll wrapper on a flat surface, place a generous spoonful of the chicken mixture in the center, and fold the sides in before rolling it tightly to seal. Use a little water to help seal the edges if needed.
Fry the Egg Rolls: Heat oil in a deep pan over medium-high heat. Once hot, carefully add the egg rolls, frying them until golden brown and crispy on all sides. This should take about 3-4 minutes.
Drain and Serve: Remove the egg rolls from the oil and drain on paper towels. Serve warm with your favorite dipping sauce, such as additional ranch or barbecue sauce.
