My 13yo seems to be constantly hungry. He's not a sporty or active boy, but he's always been skinny and had a small appetite. Until now.
What can I fill him up with, without blowing my food budget? He prefers sugary, snack foods, but I don't want to give him carte Blanche to fill up on rubbish. He's a tad on the lazy side so won't bother to make much effort to prepare himself anything proper.
What's cheap, filling, quick to prepare and won't have me running to the supermarket to restock daily?
