Winter is usually the time we enjoy tomato soup but this roasted tomato soup is perfect on a cold, wet spring day. Roasting tomatoes in your slow cooker intensifies their flavor. This roasted tomato soup is flavored with herbs and garlic and simmered with chicken broth, ricotta and Parmigianino cheese. Top the soup with a dollop of spinach pesto and you are in for a real treat. The soup needs to cook for six hours. The spinach pesto can be made ahead and stored in the refrigerator for up to one week or in the freezer for up to 6 weeks.
