Bring a pot of water to a boil. Carefully lower eggs into the pot and cover. Reduce the heat to a simmer and boil for 10 minutes.
Meanwhile, prepare an ice bath and toast your bagel.
When eggs are done, immediately place in ice bath and allow to cool down.
Peel eggs and separate the yolks from the whites. Chop the egg whites and set aside.
Place egg yolks, Greek yogurt, dijon mustard, garlic powder, sriracha (if using), salt and pepper in a bowl. Mix until creamy.
Stir in chopped egg whites.
Use as filling for a sandwich or bagel, or serve with wholewheat crackers or veggie sticks. Enjoy!
