Spread 2 tablespoons peanut butter over 1 slice of bread. Spread 2 tablespoons jam on a second slice. Put the two pieces of bread together to form a sandwich. Cut off the crusts and cut the sandwiches into fourths. Repeat with remaining 6 bread slices.
Divide the PB&J sandwiches, cheese sticks, baby carrots, celery and ranch dip into meal prep containers.
