I've made a chicken casserole using defrosted chicken and put it all together with carrots, peas, onions and mushrooms and used a colemans mix but haven't cooked it yet and now plans have changed so its not going to get eaten tonight but I don't want to waste it. Do I cook it and fridge it and use tomorrow night or can I just out the whole thing raw in the fridge for tomorrow or is it scrap?
