Yesterday I made a double portion of bolognaise sauce with quorn mince. Normally I'd just use it the next day but I have chicken that needs to be eaten so I froze it instead. I've never frozen food before so I don't know what to do with regards to reheating it. Do I need to let it totally defrost before cooking or can I just put it in the microwave and cook it from frozen? Also - would it be different if there was meat in it?
