Add the chopped Romaine to a lunch container. Top with the hard-boiled egg, avocado, cucumber, whole cherry tomatoes, blue cheese, bacon, and sliced cooked chicken.
Pack the dressing
Pour your favorite dressing into a small lidded container and pack it separately so the lettuce stays crisp.
Pack for school
Close the container and refrigerate until ready to pack. Place it inside an insulated lunch bag with an ice pack and keep chilled until lunchtime. Add the dressing right before eating.
