Hard boil eggs. Bring large pot of water to a boil. Add eggs and cook for 12 minutes. Right at 12 minutes drain hot water and run with cold water for 2-3 minutes. Let eggs sit in cool water. Once cooled, peel eggs.
Using a slicer or my hand, dice eggs into small pieces. Add to a large bowl.
Add in celery, green onion, and relish.
In a small bowl, whisk together yogurt, mayo, dijon mustard, salt, pepper, and lemon.
Pour dressing over top of egg mixture and stir everything until well combined.
Serve on toast, with crackers, or eat as is! Store in fridge.
