This makes a lot..I probably used half for 4 servings of noodles.
For the baked mac I added some home made bread crumbs from some left over home made bread in the freezer. Just toasted it and put in in the food processor w/ a bit of olive oil and simply organics all purpose seasoning. I bake at 350 until the top gets toasty and brown.
