Italian Chicken Minestrone

In a large pot, heat oil over medium-high. Add onion and cook until softened, 8 minutes. Add garlic and cook until fragrant, 30 seconds. Add tomatoes with juice and cook until liquid is evaporated, 4 minutes. Add broth and bring to a boil. Add pasta, carrots, and Parmesan rind, if using, and cook 5 minutes. Add kale, zucchini, and chickpeas and cook until zucchini is crisp-tender, 5 minutes. Stir in chicken and cook until warmed through, 1 to 2 minutes. Season with salt and pepper and remove rind before serving. Sprinkle with Parmesan, if desired.
