"Leftovers are your best friend," according to Bec of theveryhungrymummy. "Leftovers mean you have one less thing to worry about in the morning. Meatballs can quickly be added to pasta or into a mini sub sandwich. Pasta can be served cold with some extra protein (like cheese or deli meat) stirred through." Bec likes to pack leftovers in a thermos or insulated lunchbox with a spot for warm foods.
