Prepare the egg salad: In a bowl, mix chopped hard-boiled eggs, diced celery, red onion, mayonnaise (or Greek yogurt), Dijon mustard, salt, and pepper until combined.
Assemble the wraps: Place a lettuce leaf on a plate. Spoon a generous amount of egg salad into each leaf.
Add toppings: Sprinkle crumbled bacon and cherry tomato halves on top.
Garnish: Sprinkle with paprika or extra black pepper for some extra flavor.
