This vegetarian soup features a rainbow of vegetables. You can use any multicolored pasta in place of the spirals. —Crystal Schlueter, Northglenn, Colorado
Cut stems from chard; chop stems and leaves separately. Reserve leaves for adding later. In a large skillet, heat oil over medium heat. Add onion and chard stems; cook and stir until tender, 3-5 minutes. Transfer mixture to a 6-qt. slow cooker.
Stir in broth, tomatoes, kidney beans, garbanzo beans, squash, pepper, carrot and garlic. Cook, covered, on low until vegetables are tender, 6-8 hours.
Stir in pasta and reserved chard leaves. Cook, covered, on low until pasta is tender, 20-25 minutes longer; stir in pesto. If desired, serve with additional pesto, Parmesan cheese, red pepper flakes and fresh basil.
