I always keep some baked sweet potatoes in my refrigerator, so putting this salad together was super-easy. It’s a great salad for fall or winter because it’s served warm!
Preheat the oven to 350 degrees F and line a baking sheet with parchment paper.
In a large bowl, combine the sweet potatoes, olive oil, salt, and pepper. (When picking out sweet potatoes at the store, make sure they are firm, and look carefully to ensure there are no signs of decay or cracking. Store them in a cool, dry, well-ventilated container -- sweet potatoes are more perishable than you think! I try to use mine within a week or so.)
Spread the potatoes in an even layer on the baking sheet and roast for about 1 hour, tossing occasionally, or until they're soft. (To help maintain nutrients, boiling or steaming sweet potatoes are also good cooking methods.)
In a large skillet, heat the oil over medium heat then add kale, tossing frequently until wilted (about 4-6 minutes).
Add the garlic and salt, and mix for an additional 2-3 minutes.
Add the red chili pepper flakes and stir to combine. Remove from heat and set aside.
In a separate pan, dry roast the pine nuts (without oil) until they’re lightly golden and fragrant (about 1 minute).
In a large salad bowl, mix the cooked kale with baked sweet potatoes, then garnish with the toasted pine nuts and serve immediately.
