Remove cooked eggs from cooker and let cool for a few minutes before peeling them (I typically run them under cold water to cool them faster!)
Place peeled eggs, mayonnaise, relish, chopped green onions and a dash of celery salt in a food processor and chop until combined but still chunky
Serve immediately on croissant sandwiches sprinkled with paprika and chopped green onions or place in an air-tight container and refrigerate until ready to use (store in refrigerator for up to 2 days)
