For a limited time only, Subway is giving away a FREE Muppets Most Wanted backpack with the purchase of a Kids Meal. These adorable Muppet-themed backpacks are the perfect size to take to a playdate, park or friend’s house. Each meal comes with a Mini Subway Sandwich, Apple Slices and Milk. I think that of all the kid’s meals out there, this one seems to be more nutritious than most! I am sure kids are going to love this promotion.
