This is such a simple soup but it's so satisfying. Potatoes, carrots, kidney beans and broth. I make this all the time and I don't use any particular recipe, but I found a recipe online that is similar to mine. To keep it vegan leave out the sour cream and flour mixture which is just basically a thickener. I actually like a thinner less starchy soup. Plus, you can thicken it by mashing up some of the potatoes. Tip--instant mashed potatoes are a good way to thicken soups and stews.
