To thicken soup: Allow soup to cool slightly. With center part of cover removed to let steam escape, puree soup in batches in blender on high speed until smooth. Return soup to saucepan and simmer until heated through.
Serving Suggestion: Serve with assorted toppings such as chopped avocado, shredded Monterey Jack cheese and chopped fresh cilantro.
Substitution Tip: Instead of chicken, use 1 1/2 cups finely chopped cooked turkey.
