Step 1

Cut or tear the kale into 1/2-inch strips. In a medium saucepan, heat 1 tablespoon oil over medium-high heat. Add onion, and cook until softened, about 5 minutes.

Step 2

Add about half of the beans, and lightly mash with a fork. Add water and stock, and bring to a boil. Stir in kale, remaining beans, 1 teaspoon salt, and 1/4 teaspoon pepper. Partially cover, reduce heat, and simmer until kale is tender, about 20 minutes.

Step 3

Toast bread. Ladle soup into bowls, top with toast, and drizzle with remaining tablespoon olive oil. Sprinkle with Parmesan, if desired.
