Ingredients

5 tablespoons olive oil

2 medium onions, finely diced

4 cloves garlic, minced

2 green bell peppers, finely diced

4 cans black beans with juice (15 1/2 ounces each )

1 1/2 cups canned black-bean puree

5 dried bay leaves

2 teaspoons ground cumin

2 teaspoons dried oregano

Salt and freshly ground black pepper

1 tablespoon white vinegar

3 tablespoons chopped fresh cilantro, plus more for garnish

2 tablespoons finely diced red pepper, for garnish (optional)

Preparation

Heat olive oil in a medium stockpot set over medium-low heat. Add onions, garlic, and bell peppers; cook until onions are soft but still translucent, about 25 minutes.

Cook mixture until thickened, about 10 minutes. Stir in vinegar and cilantro. Garnish with more cilantro and the red pepper, if desired.
