6 tablespoons olive oil
2 leeks (white and light green parts only), sliced
2 bunches Tuscan or Lacinato kale or 1 medium bunch curly kale (about 20 ounces total), thick stems discarded and leaves sliced
4 cups low-sodium vegetable broth
2 15-ounce cans butter, cannellini, or corona beans, rinsed
1 28-ounce can diced tomatoes
kosher salt and black pepper
1 ounce Parmesan, grated (about ¼ cup), plus more for serving
6 thick slices country bread, toasted
Heat 2 tablespoons of the oil in a large pot or Dutch oven over medium heat. Add the leeks
Add the broth, beans, tomatoes (and their juices), 1 teaspoon salt, and ½ teaspoon pepper and bring to a boil. Reduce heat and simmer, partially covered, stirring occasionally, until thickened, 20 to 30 minutes. Stir in the Parmesan.
Tear the toasted bread into large pieces and drizzle with 2 tablespoons of the oil. (I served the bread on the side. Homemade bread, of course!)
Serve warm topped with the bread. Drizzle with the remaining 2 tablespoons of oil and sprinkle with additional Parmesan.
