After years of our annual Chili Cook Off tradition, we changed it up this year and had a Soup Cook Off, which was not only a lot of fun, but extremely delicious! We had 10 amazing homemade soups to vote between, and the decision was not easy -- every soup was incredible! The grand prize went to a delectable Baked Potato Soup (topped with green onions, cheese and bacon 😲😲🤯🤯), and tied for second place were a Chicken Pot Pie Soup and a Gumbo with Chicken and Andouille Sausage. Aren't you hungry just reading this?! 😂 Are you a soup aficionado? Drop us a comment about your favorite soup recipe, or comment which soup from the list of contenders you'd be most interested to try. It is soup season after all! ... See MoreSee Less
