It's a bolognese sauce of course, but I am making it with fake meat, so it's a nolognese, or perhaps spaghetti and neatballs.
The ingredients aren't any surprise: tomato, onion, spices, olive oil. The part I don't see so often is carrot, which is shredded or pureed and added for sweetness. This means that I don't have to add salt or something sweet to cut the acidity.
If I'm doing it for vegans or nondairy folks I omit Isa's last step: a tiny amount of milk at the end.
