I Just Learned Parmesan Isn't Vegetarian, And I Had No Idea

Like many of us, I’ve dabbled with vegetarianism and even had a brief vegan phase. 

About 5-7% of the UK population are vegetarian, YouGov says, with 64% having started the lifestyle in the past five years. 

While veggie dining options might have moved on from the sad mushroom burgers of years gone by (why was it always so soggy?), cheeses like the mozzarella on a margarita pizza have always seemed like a safe bet. 

But it turns out that Parmesan, a common pasta add-in, doesn’t count as vegetarian at all.
