In a large mixing bowl, combine shredded chicken, cream cheese, and diced sausage (if using). Add chopped green onions, grated cheddar cheese, hot sauce, and Cajun seasoning. Blend until creamy.

Lay an egg roll wrapper in a diamond shape. Spoon 2 tablespoons of filling and fold the corner over the filling, tucking sides and rolling up tightly. Seal edges with beaten egg.

Heat vegetable oil in a skillet to 350°F (175°C). Watch until the oil shimmers.

Fry 3 to 4 egg rolls for 3-4 minutes, turning occasionally until golden brown. Remove and drain on paper towels.

Serve hot on a platter with your favorite dipping sauces.
