Reheating a cheese sauce?

[cairnterrier]

Last night I made macaroni cheese but with bits of ham and cooked cauliflower in. The latter was because DS is a vegetables refuser and I thought white vegetables in a white sauce............... I thought wrongly.

Anyway, there's still half a dish of the stuff left which I was going to have cold for dinner but it's such a horrid day here that the thought of something hot for dinner is quite appealing. So can I reheat it? If so, how would you do it? In a saucepan (appearance is not important) or shove it back in the oven. Am pregnant so need to be a little bit cautious about food poisoning etc.

Thanks

I reheat my cauliflower cheese from Sunday dinner, most Monday nights, for either me or DD. Sometimes in the oven, sometimes in the microwave. Neither of us have ever been ill. It's nicer second time round too!

Should be fine. Make sure it's hot all the way through. I always reheat the next day.
