Grilled sausages with mashed spuds and side salad. Vary the spuds by mashing in leek fried in butter or a generous dollop of whole grain mustard.
And now I'm laughing because I have just noticed I have put the same suggestion as Mayday. Good English grub, nice and easy and filling.
Colcannon is an Irish version of the same theme, cabbage mashed in with spuds, generally served with cooked ham or bacon.
Make sure there is plenty of salted butter mashed in with the spuds.
Then try swede mashed in with the spuds. Or a combination of mashed parsnips and carrots browned off in the oven or under the grill. All very easy and filling comfort food for winter.
