Curious George

Chef Pisghetti has come up with a new recipe for Giardino Burgers-hamburgers containing no meat. He trusts George to take a box of prepared burgers out to his truck to get sent to the annual firefighter's picnic but George accidentally puts them on the wrong truck. Having lost the burgers George recalls that the chef's recipe was all pictures. He finds the notepad where the chef had drawn everything and finds the recipe for the burgers. Or is it the Chef's plan to expand his rooftop garden?
