Varies - DH and I quite like a nut roast, DS and my wider family aren’t really interested.
So if it’s just the three of us, DH and I have a nut roast and DS just has a tonne of veggies which is what he actually wants anyway (roast potatoes, sprouts, carrots, swede, red cabbage, parsnips, cauliflower cheese, Yorkshire pudding). If DM or DBro are coming, I make or buy a mushroom wellington or some kind of filo tart, plus veggies.
