The Mommy Meal was a healthy lunch Susan had packed for Greg in Diary Of A Wimpy Kid: The Long Haul. Susan got the idea from the magazine "Family Frolic". Greg had originally asked to eat at a fast food place during the road trip, but Susan said that fast food places don't serve "real food" and that she had something even better planned.
Inside the Mommy Meal there was a tuna sandwich, an orange, a carton of milk, and a "prize" in foil which you could only open once you'd eaten the fruit. (which was really just a pack of math flash cards). The activities include a word scramble that when unscrambled says Summer Learning Is Fun, a joke, a Capitals Crossword and an activity named "Name that Nobel Prize winner!".
