Creating Greek Yogurt Egg Salad Croissants is simple and can be done in just a few steps:

1. Boil the Eggs: Place the eggs in a pot and cover them with water. Bring to a boil over medium heat. Once boiling, cover the pot and remove it from heat. Let sit for 10-12 minutes.
2. Cool the Eggs: After the eggs have cooked, transfer them to an ice bath to cool for about 5 minutes.
3. Peel the Eggs: Once cooled, peel the eggs and chop them into small pieces.
4. Mix the Ingredients: In a mixing bowl, combine the chopped eggs, Greek yogurt, Dijon mustard, chives, dill, and celery. Stir until well combined.
5. Season: Add salt and pepper to taste, adjusting according to your preference.
6. Prepare the Croissants: Slice the croissants in half lengthwise.
7. Fill the Croissants: Generously spoon the egg salad mixture onto the bottom half of each croissant.
8. Add Lettuce (Optional): If desired, place a leaf of lettuce over the egg salad before closing the croissant.
9. Serve: Place the top half of the croissant back on and serve immediately.

These steps will guide you to create your Greek Yogurt Egg Salad Croissants with ease.
