How to Make It
Heat oil in a large Dutch oven over medium-high heat. Add onion and garlic; sauté 3 minutes or until tender. Add 3 cups water and next 8 ingredients (through cannellini beans), stirring to combine.
Combine remaining cup of water and tomato paste in a bowl, stirring with a whisk until blended. Stir tomato paste mixture into bean mixture. Bring to a boil; reduce heat, and simmer 5 minutes or until thoroughly heated. Ladle soup into bowls. Top with cheese, if desired.
