In March, Green Toys will introduce their foray into play food. Using the company's recipe for converting used milk cartons into eco-friendly toys, a set that allows tots to create their own pizza parlor ($25) has been designed. Each set will come with four crusts and stackable toppings to create the ultimate pie. Cardboard pizza boxes and an order pad are also included. Best of all — it's all dishwasher safe, should someone feel the need to try to take a real bite out of it!
