What to Serve with Chicken Soup

We like to top our bowls of soup with shredded cheese, sour cream, and a squirt of fresh lime juice. It is equally delicious with some tortilla chips and sliced avocado or guacamole. Whip up a Mexican Chopped Salad or some cornbread if you aren’t doing keto. One bite and this is sure to become a family favorite!
