Oh yeah those. Yeah that’s one of the ways to eat beans in the US (with sausage and onions), but it’s the third that comes to my mind personally. When I think beans, my first thought is Mexican refried beans, with salt, lime, probably some other stuff I’m not sure, and topped with a pinch of Queso. Not remotely sweet. Then I think of our chili’s, which are usually pretty bean heavy too, how sweet they are depends on where it came from. In my experience it’s mostly just the storebought chili’s that have any sugar, I don’t think people consider adding any to their homemade stuff.
