Over in an hour ...... not in my house!
Tomorrow I will have to return to the kitchen and make something from scratch!!
Finally sprinkle over the grated cheeses and heat in the oven. If cooking from hot it will only require 20 minutes or so, until the cheese is bubbling. If re-heating from cold it will need 30 - 40 minutes.
Or, you could of course use pumpkin.
I sometimes add a little crushed dried chilli too.
