"Eyes bigger than your belly" was a common accusation levelled at me growing up, so with a crushing inevitability I always make to much food. This includes baked potatoes. Last night I coupled up some Lebanese Lentils with a baked potato that had been languishing in the fridge for a few days. It was a hit - and dead simple.
One cooked baked potato
Salt and pepper
Carefully slice the potato into 5-10 mm wide slices (try not to let them fall apart)
Fry in the oil on a low or medium heat - take your time as this works better if cooked slowly
Season on each side with salt and pepper as you cook
As I did, with some light and lemony like a salad or similar... Unless you've got a hangover in which case this would be bob on with vegan sausages, mushrooms, beans etc etc etc...
