Preheat oven to 400°F (200°C). Chop sweet potato into 1-inch cubes and toss with olive oil, salt, and pepper. Roast for 20-25 minutes, or until tender.
While sweet potatoes are roasting, massage kale with olive oil and a pinch of salt until tender.
In a large bowl, combine roasted sweet potatoes, massaged kale, cranberries, and pecans.
Whisk together dressing ingredients (see recipe for details) and pour over salad. Toss to combine.
Notes
This salad is best served immediately, but leftovers can be stored in the refrigerator for up to 2 days.
