Recipe Quest Game. Players select a Recipe with food items displayed, and must find those items hidden on a map. You can add some obstacles (enemies, puzzles, etc) to make it challenging to find. When they find all the ingredients to complete the recipe, a new recipe is unlocked. Use real-world recipes, so the game can actually be applicable in real-life, so the game can function secondarily as a interactive cookbook 
One of my favorites is Spaghetti!
