Frozen leftovers

[isthistoonosy]

I've got some frozen left overs from xmas (turkey, roast potatoes, roast veg) and wondered what's the best way to reheat them so we don't have soggy potatoes etc.

Roast potatoes make good bubble and squeak, roast veg can become soup, if you don't aim to get them back to their original state but do something else with them, you should be fine.

I did bubble and squeak with the whole lot, chopped up meat, veg & potatoes, pan fried with a bit of grated cheese on... mmmmm

I sound dense but I've only eaten bubble and squeak a few times as a kid how do I make it what binds the veg and potatoes together?
