Thanks for the feedback – I've improved it based on that.
The distinction of pepperoni/chilli in german is unclear indeed – from my supermarkets it seems to be pepperoni for green and medium spicy and chilli for red and very spicy, but it's not consistent. This article tells the difference is in the spiciness and taste… Haven't figured out a way to depict this uncertainty yet.
As for the black pepper: My idea was, that in English afaik 'black pepper' is often used as an umbrella term
 for black/white/green pepper. But I now added the other terms as well.
