01 - In a large bowl, combine the chicken, mayonnaise, chili crisp, Dijon mustard, celery, red onion, and herbs if using. Mix thoroughly until all ingredients are evenly distributed.
02 - Add lemon juice to the mixture, then season with salt and pepper to taste. Stir well to incorporate and adjust seasoning as needed.
03 - Lightly toast the sandwich rolls or bread slices if desired for added texture and to prevent sogginess.
04 - Place salad greens on the bottom half of each roll or bread slice. Arrange sliced cucumber and tomato evenly over the greens.
05 - Spoon a generous portion of the prepared chicken salad onto the vegetables. Drizzle with additional chili crisp if you prefer extra spice.
06 - Top with the remaining bread half, press gently to secure, and serve immediately while the vegetables are crisp.
