In a medium bowl, combine cooked chicken, mayonnaise, and chili crisp. Stir until well-coated and creamy. Add sesame seeds, peanuts, and green onions, mixing evenly.

Season the mixture with salt and black pepper to taste. Start with a pinch of each and adjust as needed.

Lay three slices of bread on a cutting board. Generously scoop the chicken salad mixture onto each slice. If using, add a layer of lettuce.

Place the remaining slices of bread on top. Cut each sandwich diagonally for easy handling.

Serve immediately or wrap tightly in plastic wrap to store for later.
