Stovetop: Add a touch of olive to a large soup pot. Cook the onions for 6-8 minutes until tender. Add the garlic and cook for 1 minute until fragrant. Add the remaining ingredients and bring to a simmer. Cover and cook for 30 minutes. To keep the chicken as tender as possible, I like to remove it after 12-15 minutes when it is cooked through. Then I shred or chop it and add it back to the soup before serving.
