Sorry if that question sounds as obvious to you as it does to me. To me I expect a pepperoni pizza to have cheese and pepperoni on it, and nothing else.
But recently we’ve been doing a tour of all the local takeaways and leaving a review for each one, which has been fun. A surprising number of them add green peppers to the pepperoni pizza, even when it’s not documented on the menu. The menu will say like,
meat feast: ham, chicken, beef;
hawaiian: ham, pineapple;
pepperoni: pepperoni
but then it arrives with additional green peppers. So I’ve got into the habit of saying “just pepperoni, no other topping”, which usually works but this week’s takeaway arrived with green peppers again anyway.
Sorry to rant, but do I just not know what a pepperoni pizza is, or is it the children who are wrong?!
Pizza places here will clearly list what is on each pizza but you can specify with or without. Generally in my experience pepperoni is usually just pepperoni but depends on the shop.
Personally though, and I’ve been told this isn’t the way, I like to have onion, peppers, chillis, olives on any type of pizza. I like a lot of variety but somebody once told me you can enjoy each flavour like that. I do though
