Step 1

Heat a large Dutch oven over medium-high heat. Add the olive oil, then carrots, celery, onion and sweet potato. Season with 1/2 teaspoon salt. Cook 8 to 10 minutes, until slightly softened. Add the garlic and cook 2 more minutes.

Step 2

Add the stock, tomatoes, corn, green beans, zucchini, cannellini beans, and Italian seasoning. Return to a simmer, then reduce heat to medium. Cook at a low simmer, stirring occasionally, until the zucchini and green beans are tender, 12 to 15 minutes. Add the spinach and stir to wilt.

Step 3

Season with the remaining 1/2 teaspoon salt and black pepper. Serve in bowls drizzled with more olive oil.
