Spread mayonnaise and mustard on each of the bagel halves.
Top the mayonnaise side with lettuce, tomato, deli turkey or ham, cheese, and close the sandwich with the other bagel half.
Pack it for lunch:
Slice the Everything bagel sandwich in half and pack it inside a lunch container. Add healthy sides, like fresh fruit and veggies, to this lunch in a separate compartment or containers.
Refrigerate until ready to pack inside a lunch bag, with or without an ice pack.
