A few medium sized potatoes, some carrots, sugar beets and celery. Sounds like another fridge raid...
Throw in a chicken breast and boil until it's done, then boil the potatoes, carrots and beets. Once done, simply shred the chicken breast, cube the potatoes and slice up the carrots and beets.
Slice up some fresh celery stalks, and place all the ingredients in a bowl. Once cooled, add in a cup and a half of mayo, some salt and pepper, and start mixing. Place in the fridge to chill.
Garnish with some celery tops and serve. Quick and easy, another successful fridge raid.
