This fragrant, Italian-flavored soup takes advantage of quick-cooking ingredients--boneless, skinless chicken breast, bagged baby spinach and canned beans. It features a simple homemade basil pesto swirled in at the end to add a fresh herb flavor. If you are very pressed for time, you can substitute 3 to 4 tablespoons of a store-bought basil pesto.
