Put the sweet potato cubes on a baking tray. Add the oil, salt, cinnamon, black pepper, and cayenne pepper, toss to coat, and spread out the sweet potato evenly.
Roast until the sweet potato is tender and starting to brown, about 20 minutes, flipping the cubes once halfway through.
Cool slightly before you assemble the salad, otherwise the hot potato will wilt the arugula.
For the Maple Ginger Tahini Dressing:
Whisk together all ingredients in a small bowl. You can add additional water 1 teaspoon at a time if needed to thin out the dressing so it’s easy to pour.
To Assemble the Salad:
Spread the arugula in the bottom of a serving platter. Arrange the roasted sweet potato cubes, sliced apple, sliced onion, pecans, goat cheese, and cranberries on top.
Serve the salad along with the dressing to drizzle on top.

Notes
Make Ahead: Roasted sweet potato is delicious warm, cold, or at room temperature in this salad recipe. You can roast the sweet potato ahead of time, so all you have to do is minimal chopping and then assemble the salad when you want to serve it. You can store roasted sweet potato covered in the fridge for up to 5 days. Additionally, you can make the tahini dressing up to 1 week ahead of time and keep it in a covered glass container in the fridge.
Recipe Yield: This serves 6 as a side dish or 4 as a main course with protein added (such as a can of beans or grilled chicken).
