Spam and Kraft Dinner!
I remember eating that on many occasions when I was a kid.
Ben! You can make mac & cheese better and cheaper than that box stuff from Kraft.
You can buy powdered cheese (dehydrated cheddar cheese) online and mix it with powdered milk, powdered butter and water, heat the mixture and then combine it with boiled macaroni. Tastes great, hasn’t the additives of Kraft Mac & Cheese box stuff, and is far less expensive because you’re not paying for packaging.
If you want the actual recipe, I will post it here.
