Still vegan if you eat similar food like this?

My friend says she's vegan and likes to bragg about it. We went to cafeteria together and she asked serving lady to give her some red sauce. Lady said that the sauce is made out of meat, but my friend didn't mind it at all. So do vegans eat foods that are made out of meat but don't contain pieces of meat then too?

Note:I'm not vegan, I'm sorry in advanced if any of this is rude, I'm just trying to understand. 😅 Thank you for help.
