It's my understanding that ikea meatballs are made from mdf materials and dust that is produced as holes are drilled in their flat pack furniture. Not a single piece of material is wasted and the meatballs are a staple of their store cafes worldwide. I'm assuming the huge build up of these meatballs will be re routed to other locations during this Christmas experiment. Perhaps future mdf meatballs will have all meat additives removed and we will begin a new era of vegan foods.
