This healthy chicken and vegetable soup recipe is perfect for when you're in the mood for comfort food and Mexican all in one! The small amount of chipotle peppers in adobo sauce gives it a mild spice level. For a spicier soup, stir in up to 2 tablespoons chipotle peppers. Look for the small cans of smoked chipotle peppers in adobo sauce near other Mexican ingredients in well-stocked supermarkets. Once opened, refrigerate for up to 2 weeks or freeze for up to 6 months.
