This quick-to-prepare, hearty soup recipe comes from Margaret Simone of Singer Island, Florida.
In a Dutch oven, cook sausage over medium- high heat, breaking it up with a spoon. Add onion and garlic. Cook, stirring often, until sausage is browned and onion is softened, about 8 minutes.
Add tomatoes and broth. Bring to a boil. Reduce heat; simmer, partially covered, until tomatoes are softened, about 10 minutes.
Stir in cannellini; simmer until heated through, 2 minutes. Season with salt and pepper. Stir in basil. Garnish with grated Parmesan and whole basil leaves.
