In the olden days there used to be something called "Instant Whip" (stop tittering at the back) which also came in butterscotch or strawberry flavour - I think Angel Delight is the upgraded variant.
Do like that pic of the steak and mushrool pud a few posts back.
For a gourmet version try making it with stilton and apricots. For us carnivores Steak and anything but kidney pudding, Harveys Old and my mum's steamed chocolate pudding with layer apple at the bottom and custard.
