The original recipe has a lot of fat, so, to cut down a bit on it, we left out the bacon, and only used about half the cheese. I am the kind of person who adds more cheese to cheese, so, you can trust me when I say you won't miss the extra cheese. I also love bacon, and didn't miss that at all either. I think the next time we try this recipe, we are going to half the roux (flour+butter), to cut down on more fat; this will result in a wetter end result, however, I don't think I will mind.
