for the posters that freeze a week's worth of sandwiches, i'm assuming not all sandwich fillings freeze well, which sandwich fillings freeze ok?
My boys only like simple fillings for school - DS1 likes butter and vegemite and DS likes hommus. The hommus can get a bit soggy so a layer of butter helps with that.
Philly cheese also freezes ok and so do jam and honey. DS1 used to like philly with jam or honey but he's gone off it now.
DS2 also likes avocado which doesn't freeze at all well so he doesn't get it often.
