I boil mine with skin on, sometimes if I remember will do it the night before, when cool skin comes off easily.
I will slice them, add hard boiled egg and bit of blue cheese dressing, that can be my lunch......
or cooked as above, saute one sliced red onion till soft, then add some dijon mustard, bit of vinegar, bit of honey and make dressing right in a pan, add toasted sunflower seeds or pine nuts....
