Use the microwave singles for Mac-N-Cheese. They are precooked. You can also add tuna (or other meats) to Lipton's Noodles/Rice and Sauce, or Idahoan Potatoes or many other such things. I think that the standard M&C will work but you have to let it set for a long time. In any case the butter or oil is not necessary. Also instant rice or couscous work fine for FBC.
