Sweet Potatoes with Warm Black Bean Salad

Ingredients:
4 medium sweet potatoes
1 15-oz can black beans, rinsed
2 medium tomatoes, diced
1 tablespoon extra-virgin olive oil
1 teaspoon ground cumin
1 teaspoon ground coriander
3/4 teaspoon salt
1/4 cup sour cream
1/4 cup chopped fresh cilantro

Directions:
Prick sweet potatoes with a fork in several places. Microwave on High until tender all the way to the center, 12 to 15 minutes. Meanwhile, in a medium microwaveable bowl, combine beans, tomatoes, oil, cumin, coriander, and salt; microwave on High until heated through, 2 to 3 minutes. When just cool enough to handle, slash each sweet potato lengthwise, press open to make a well in the center and spoon the bean mixture into the well. Top each with a dollop of sour cream and a sprinkle of cilantro.
