I told you I wasn't kidding with the mac! This was last Friday's mac. I previously made a vegan version of this recipe and it was really good, gotta post that recipe. This one on the other hand was using what I had on hand, which was some milk, white cheddar, mustard greens, and a corner of Jarlsberg cheese I had. The cook's thesaurus says that Emmentaler, Gruyère , Swiss, or raclette will work to sub for the Jarlsberg.
