Dinner tonight is being troublesome!!

Making meatballs for the slow cooker and it's just dawned on me that we have no eggs - and my shopping is being delivered between now and 5pm so I can't leave to get any! What can I use instead??

Was going to slow cook a leg of lamb....but it's too big for the cooker so DH needs to cut through the bone to make it fit. So that's now tomorrow! Gah!!!
