I don't understand the assumption that vegan = shite.
One of my work clients has a canteen that is about half vegan, with most of the rest vegetarian and they might serve a couple of fish or chicken dishes across the week.
The food is made from vegetables, pulses, grains, cheese, eggs, fruit and dairy. You know, normal food that everyone eats that just happens to be vegan or vegetarian.
The university isn't going to 'end the climate crisis' whatever it serves in it's eateries though.
