Egg Greek Cucumber Sandwich

Slice cucumber and onion thinly.

Boil the eggs, let them cool, and peel off the shells.

In a bowl, mash and mix the boiled eggs, Greek yogurt, salt, and pepper well.

Mix the sliced cucumber and onion to prepare the salad filling.

Layer the egg-Greek mixture and cucumber salad on whole wheat bread, one after the other.

Cover with another slice of bread to form a sandwich.
