Tuna can, crackers, maybe some cherry tomatoes. This bare-bones low calorie lunch box is for those days when quick and easy beats everything else.
Drain the canned tuna thoroughly to remove excess liquid and place in a mixing bowl.
Add lemon juice, black pepper, and kosher salt to the tuna; gently mix with a fork until evenly blended.
Arrange whole wheat crackers in a snack box or lunch container, spacing them to prevent sogginess.
Spoon the seasoned tuna mixture onto each cracker or keep it in a separate compartment for easy assembly later.
Place cherry tomatoes in a section of the snack box, ensuring they’re dry to keep the crackers crisp; seal and refrigerate until ready to serve.
