Ingredients

2 tablespoons extra-virgin olive oil

1 onion, diced

2 cloves garlic, chopped

2 carrots, peeled and diced

2 stalks celery, diced

Coarse salt and freshly ground black pepper

1 can (15 ounces) whole tomatoes, chopped (juice reserved)

1/2 pound small red potatoes, scrubbed and diced

1 can (15 ounces) white beans, drained and rinsed

1 bunch kale (1 pound), stems removed and leaves torn into small pieces

1/2 cup freshly grated Parmesan

Preparation

Heat oil in a large pot over medium heat. Add onion, garlic, carrots, and celery and season with salt. Cook vegetables, stirring, until tender, about 8 minutes.

Increase heat to medium high and add tomatoes and their juice. Cook, stirring, until mixture begins to caramelize, about 3 minutes.

Add 7 cups water, potatoes, and beans, and bring soup to a boil. Reduce heat and simmer until potatoes are tender, about 10 minutes, then stir in kale.

Cook, covered, until tender, about 2 minutes, then season with salt and pepper. Top with Parmesan.
