Get one of the cheap plastic mandolins. Makes slicing taters a breeze and you will do it more often. I fry in vegetable oil. Slice an onion or two in a skillit full. I just wash mine with a brush and slice them skin and all. Not much better eating no matter what you cook with them. Salt Pepper and a dash of Cumin.
I try to take one day at a time, but sometimes several days attack me at once.
