My reply was that crisps and biscuits won't keep hunger at bay for very long, you should really be asking for potatoes and veg.
Boil the different veggies and pour a cheese sauce over means you seem to like pizza.
The potatoes you can boil or bake, and again cheese sauce.
They came back saying they didn't like this and that, so I said then you can't be very hungry then, because you would eat anything given.
