Ingredients

5 tablespoons extra-virgin olive oil

1 medium onion, halved and thinly sliced (2 cups)

1 1/2 pounds green beans, trimmed and halved crosswise on the bias

1 can (28 ounces) whole peeled tomatoes, drained and coarsely chopped (2 cups)

1 cup low-sodium chicken or vegetable broth

2 tablespoons coarsely chopped fresh oregano leaves

Kosher salt and freshly ground pepper

Preparation

In a large straight-sided skillet or a wide, shallow pot, heat 2 tablespoons oil over medium-high. Add onion and cook until translucent, about 3 minutes. Add beans, tomatoes, broth, and oregano, stirring to combine; season with salt and pepper. Bring to a boil. Reduce heat to medium, cover, and simmer, stirring occasionally, until beans are very tender, 18 to 20 minutes. Stir in remaining 3 tablespoons oil and season with salt and pepper; serve.
