Creamy egg salad on soft bread is a protein-rich, vegetarian-friendly sandwich that's easy to make in batches. This classic lunch option is a family favorite for picnics and quick meals.
Place the eggs in a saucepan and cover with cold water by an inch. Bring to a boil, then reduce heat to low and simmer for 10 minutes.
Remove eggs from hot water and transfer immediately to an ice bath. Let them cool for 5 minutes, then peel carefully.
Chop the cooled eggs into medium chunks for a creamy but textured salad.
In a large bowl, combine chopped eggs, diced celery, and red onion. Gently fold in mayonnaise, Dijon mustard, lemon juice, salt, and black pepper until evenly mixed.
Lay out the bread slices and spoon the egg salad mixture onto half of them. Top with the remaining slices to form sandwiches. Serve immediately or wrap for later.
