01 - Preheat the oven to 400°F and line a baking sheet with parchment paper.
02 - Spread the diced sweet potato on the prepared sheet, drizzle with olive oil, season with salt and pepper, and toss to coat evenly. Roast for 20 to 25 minutes, stirring halfway through, until tender and golden. Allow to cool slightly.
03 - Place the chopped kale in a large bowl, sprinkle with a pinch of salt, and massage it with your hands for 1 to 2 minutes until softened and color deepens.
04 - Add the roasted sweet potato, sliced red onion, apple slices, and pomegranate seeds to the kale and gently toss to combine.
05 - In a small bowl or jar, whisk together olive oil, lemon juice, orange juice, Dijon mustard, honey or maple syrup, salt, and pepper until emulsified.
06 - Pour the dressing over the salad mixture and toss thoroughly to coat all ingredients.
07 - Top the salad with chopped nuts and crumbled feta cheese if desired. Serve immediately or allow to rest for 10 minutes to blend flavors.
