Should I trust packed sandwiches in cafes (containing pesto) stating they are suitable for vegetarians?
It is a little known fact that a lot of pestos contain parmesan (which contains rennet, usually made with the stomach lining of calfs)
However vegetarian pesto does exist. I’ve noticed the sandwiches that contain pesto sold in cafes, state they contain basal pesto. But I’ve also heard that just because it is called basal pesto, that doesn’t always mean it is vegetarian.
Could someone shed some light on the facts on this?
