Place 1 thawed peanut butter and jelly sandwich into the largest compartment of each container.

Measure out 1/2 cup of Goldfish crackers for each container and place them in a secondary compartment.

Divide the 1 cup of celery sticks and 1 cup of baby carrots evenly among the remaining vegetable compartments, placing about 1/4 cup of each into the 4 containers.

Secure the lids tightly on all containers and store in the refrigerator for up to 4 days.
