Cook the onion in the olive oil over medium heat for 5 minutes, in a large saucepan. Stir in the celery and cook 5 minutes more. Add the Amore Tomato and Garlic Pastes, beans, broth, and water. Bring the soup to a simmer and cook 10 minutes, stirring occasionally and mashing the beans with the back of the spoon. Season to taste with salt and pepper. Add the pasta and cook 8 to 10 minutes more or until the pasta is tender. Stir in Amore Pesto Paste, if using. Serve hot.
