1Bake potatoes and allow to cool.
Dice bacon, slice onions, mince garlic, and chop celery, simmer in soup pot in olive oil till tender. When veggies are tender and bacon is done, add diced potatoes.

NOTE: Allow soup to cool for a while, or even refrigerate overnight, the longer it sits, the more flavorful it gets!
