Egg salad tramezzini are creamy, satisfying, and quintessentially Italian café fare. A vegetarian high protein mediterranean snack well-suited for clean eats and light family lunches.
Boil the eggs: Place eggs in cold water in a saucepan, bring to a gentle simmer over medium heat, and cook for 10 minutes.
Immediately transfer boiled eggs to a bowl of ice water to stop cooking, then peel and finely chop once cooled.
In a mixing bowl, combine chopped eggs, mayonnaise, olive oil, salt, and black pepper, stirring gently to maintain the creamy texture.
Lay out sandwich bread slices and trim crusts; arrange lettuce on half of the slices, then top with the egg salad mixture.
Press the remaining bread slices over the filling, slice sandwiches diagonally, and serve immediately to enjoy the soft, moist tramezzini texture.
