Ingredients

2 teaspoons olive oil

2 scallions, thinly sliced

1 garlic clove, minced

1/2 teaspoon dried oregano

1 can (14 1/2 ounces) vegetable broth

1 can (19 ounces) white beans, rinsed and drained

1 1/2 teaspoons fresh lemon juice

Coarse salt and ground pepper

2 tablespoons freshly grated Parmesan, for serving

Preparation

In a medium saucepan, heat oil over medium. Add scallions, garlic, and oregano; cook, stirring frequently, until scallions begin to soften, about 3 minutes.

Stir in broth and beans; cook until heated through, about 4 minutes. Using a wooden spoon or potato masher, lightly mash some of the beans to thicken the soup. Stir in lemon juice; season with salt and pepper. Before serving, sprinkle with Parmesan.
