Hope you don't mind a meat-eater asking for advice.
At the weekend I have a few people coming around for a pre-Christmas get-together and I am cooking a meal. One of the guests is vegetarian (not vegan). Now please don't think I am a clueless meat-eater who can't conceive of a meal without meat. We quite often eat veggie things and if it was just one person who was visiting and was veggie I would cook a veggie meal for all of us to eat. However, in this instance I think most of the guests are expecting a "proper" Sunday dinner of roast meat and vegetables and if I did that for everyone else and something completely different for the vegetarian guest I thought it would look a bit odd. So I have decided to cook a joint of meat, lots of vegetables and roast potatoes (roasted in olive oil of course not goose fat!) but provide a meat alternative for the veggie guest so he is eating mostly the same as the rest of us. I have been assured that he likes Quorn so I bought some Quorn peppered steaks.
Anyway, for everyone else there will be a jug of gravy made from meat juices. But what should I serve to veggie guest? I am worried the meal will be a bit dry without anything but I don't know what a vegetarian equivalent of gravy is. Does anybody have any suggestions please?
