How long to reheat cooked chilled lasage?

[ellasmum1]

In a conventional oven?what temp and for how long?Don't want to poison guests!!

I would say on the top of my head. 200, not sure what gas mark and for about 30-40 minutes.

According to \link{http://www.handbag.com/food/rozq&a8/\here}, 180C for 30-40 minutes... although that seems a bit long to me?

Ooh - just replied to other post

Thankyou!!
