Veggie burger is the flashy headline that makes you click stuff. What actually is happening is that they are creating a framework for stricter definitions(for many things, like sausages) that will be adopted by 27 countries in 24 different languages.

The "veggie burger" can be in the text of Malta or Ireland but who knows. They are talking about protecting some words. There are so many languages in EU, everyone calls these things differently. There's something similar against calling things not made from dairy milk or yogurt.

Vegans are infuriated apparently, maybe they can join forces with the libertarians and topple the EU so they can fight among themselves in peace.
