Thanks though that's good to know...randome question, if you didn't reheat your Bolobnese (!) in the microwave how did you do it? Just on the hob? (Sorry if this is a dumb question...my mum was definitely from the microwave-it-all school of motherhood so this is all new to me!!).
And yes, I made the pie with a low salt Kallo stock cube and no other salt so I think it will be fine?
