1. In a large bowl, combine the shredded cooked chicken, crumbled crispy bacon, shredded mozzarella cheese, ranch dressing, garlic powder, onion powder, and black pepper. Mix the ingredients thoroughly until they are evenly distributed and the filling is well-combined.

2. Lay an egg roll wrapper on a clean surface, with one of the corners facing you. Place approximately 2-3 tablespoon of the filling in the center of the wrapper. Fold the bottom corner over the filling, then fold in the sides and tightly roll the wrapper up, sealing the top corner with a bit of water to secure the roll.

3. In a deep skillet or fryer, heat the oil to 350°F. Carefully add the prepared egg rolls to the hot oil, frying them in small batches to maintain the oil temperature. Fry the egg rolls for 3-4 minutes, or until they are golden brown and crispy. Remove the fried egg rolls from the oil and drain them on paper towels.
