DH is home from work with a sickness bug and he caught me with my secret snack which I have most afternoons before he gets home - baked beans, cold, straight from the tin with little chunks of extra mature cheddar cheese stirred in.
He thinks it's disgusting. I think it's heaven in a tin. I said everyone has a secret 'gross food' they love, he says they don't!
Who's being unreasonable here!? 
I've always hidden it from him, probably because deep down I know it's a bit different.
What are your sneaky snacks that no one knows about?
