Served with chips and crackers
In a large mixing bowl, combine the diced cooked ham, mayonnaise, Dijon mustard, chopped celery, and green onions.
Add salt and black pepper to the mixture, then stir until all ingredients are well combined.
Cover the bowl with plastic wrap and refrigerate for at least 30 minutes to allow flavors to meld.
Serve the ham salad on lettuce leaves with chips and crackers on the side.
