The italian counterpart of what english speakers call "bolognese sauce" would be "ragù alla bolognese". I've never heard anyone call it "salsa bolognese", it's mostly called "ragù" only as it's most common type.
Nonetheless ragù alla bolognese is made with ground beef and tomato sauce, so the italian version is simply wrong. Try and ask for ragù recipe instead. :)
