Wisconsin who make and market and promote cheese.
I didn't measure anything as I made it, but this is the kind of dish where you make it to taste, anyway.
I started with elbow macaroni. I was thinking about spaghetti, but I didn't have any, but I had half a box of elbow mac. I cooked that in boiling salted water.
Meanwhile, I made a roux with about 2 tablespoons each of butter and flour, and added milk to make a sauce. I added a generous amount of white pepper, then I added some processed brick cheese spread. I added the drained noodles to that.
I diced some ham and some Swiss cheese and added some frozen peas, and I added all that to the macaroni and sauce. I put all than in a baking dish - actually a ceramic pie dish. Then I topped that with some shredded cheese (are you seeing the cheese theme here) then I baked it until it was bubbling and it was browning a bit on top.
Okay, it was like mac and cheese with ham and peas. It was pretty good for not having a recipe or a clue before I started.
