Ingredients
2 cans (each 15.5 ounces) black beans, drained and rinsed
2 tablespoons extra-virgin olive oil
1 white onion, chopped (2 cups)
1 large poblano pepper, ribs and seeds removed, chopped
Kosher salt
2 cloves garlic, minced (2 teaspoons)
1 tablespoon minced chipotle in adobo
1 large sweet potato, peeled and cut into 1/2-inch pieces (2 cups)
1/4 cup quinoa, rinsed
Fresh cilantro and shredded cheddar, for serving
Preparation
In a food processor or blender, purée half of beans with 1/2 cup water; set aside. Heat oil in a pot over medium-high. Add onion and poblano; season with salt and cook, stirring occasionally, until onion turns golden in places, 6 to 8 minutes. Add garlic and chipotle; cook, stirring frequently, until fragrant, 1 to 2 minutes.
Add sweet potato, remaining whole beans and puréed beans, and 3 cups water; bring to a boil, then reduce heat to low and simmer 5 minutes. Stir in quinoa. Continue cooking, stirring occasionally, until mixture reduces to the consistency of a thick stew and sweet potato is tender, 15 to 18 minutes. Season with salt and serve with cilantro and cheddar.
