Ugh, I've left uni now, but when I was there I was in a house of omnis. They even used to try and trick me in to eating meat! Mad I was. But it was all in good fun, I don't think I ever actually did.
Anyway, they would quite happily eat my vegetarian pizza made with a wholemeal pizza base, tomato paste, bell peppers, tomatoes, tonnes of spinach, fake bacon, spices and fake cheese.
And my spicy potato wedges and any interesting salads I made.
