What I call B&S is Colcannon with cooked ground beef added. Either way, it’s great stuff! Next morning I reheat it in the skillet and have it for breakfast, with hot sauce. I did a quick recipe search over the internet, and it looks like B&S can be made with or without the beef. And Colcannon never has ground beef, but sometimes has bacon (like I make it) and sometimes has sausage.
