Sweet Potato & Black Bean Chili

1 tablespoon plus 2 teaspoons extra-virgin olive oil
1 medium-large sweet potato, peeled and diced
1 large onion, diced
4 cloves garlic, minced
2 tablespoons chili powder
4 teaspoons ground cumin
1/2 teaspoon ground chipotle chile (see Note)
1/4 teaspoon salt
2 1/2 cups water
2 15-ounce cans black beans, rinsed
1 14-ounce can diced tomatoes
4 teaspoons lime juice
1/2 cup chopped fresh cilantro

PREPARATION

Heat oil in a Dutch oven over medium-high heat. Add sweet potato and onion and cook, stirring often, until the onion is beginning to soften, about 4 minutes. Add garlic, chili powder, cumin, chipotle and salt and cook, stirring constantly, for 30 seconds. Add water and bring to a simmer. Cover, reduce heat to maintain a gentle simmer and cook until the sweet potato is tender, 10 to 12 minutes.

Add beans, tomatoes and lime juice; increase heat to high and return to a simmer, stirring often. Reduce heat and simmer until slightly reduced, about 5 minutes. Remove from heat and stir in cilantro.

Make Ahead Tip: Cover and refrigerate for up to 3 days or freeze for up to 3 months.
