In a large bowl combine eggs, tuna, celery, online, olives, peas, dill weed, salt and pepper.
Drizzle mustard over top of combined ingredients
Add cooked, drained macaroni and stir until combined.
Add mayonnaise a bit at a time to combine. Keep adding until it is how you like it.
When you take it out of the fridge you may need to add some more mayonnaise as the pasta tends to soak it up as it cools.
I generally will cook an additional egg to slice on the top to decorate.
