(adapted from Epicurious)
3 tbsp olive oil
3 medium sweet potatoes (I guess they’re actually yams? The ones that are orange inside…), diced
3 cups cooked black beans (or 2 cans), rinsed and drained
juice of 2 limes
zest of 1 lime
1 tsp salt, divided
pinch or two cayenne
1/4 cup chopped cilantro
Preheat the oven to 450 and line 2 baking sheets with parchment or silpats.
Toss the diced sweet potatoes with oil and 1/2 tsp of salt and spread evenly on the prepared baking sheets.
Bake about 20 minutes (time will depend on the size of the sweet potato pieces), or until tender. Remove and let cool for about 5 minutes.
While the sweet potatoes are baking, whisk the lime zest, lime juice, remaining salt, and cayenne together in a large bowl. Add the black beans and sweet potatoes (after cooling slightly) and toss well. Sprinkle with cilantro, toss again, and serve.
