How to Make It
Mix hard-cooked eggs, onion, celery, sweet pickle relish, mayonnaise, sour cream, dried salad seasoning, Dijon mustard, salt, sugar, and pepper in a bowl until blended. Cover and chill 3 hours.
Evenly spread egg mixture on 1 side of 11 bread slices. Create sandwiches by topping with remaining slices. Cut each sandwich horizontally to create 4 finger sandwiches.
For testing purposes only, we used McCormick Salad Supreme Seasoning and Pepperidge Farm Very Thin Sliced White Bread.
