In a medium mixing bowl, add peeled and cubed sweet potatoes, 2 tablespoons olive oil, salt and pepper. Stir to combined so that the sweet potatoes are coated. Transfer to a parchment lined baking sheet and baking for 20 minutes. Stir halfway through so that the sweet potatoes are evenly roasted. They should be fork tender when done. Remove from the oven and let them cool.
While the sweet potatoes are in the oven, make the dressing. In a small bowl, whisk together the apple cider vinegar, dijon mustard, maple syrup, olive oil, garlic powder, salt and pepper.
In a large salad bowl, combine arugula, toasted pecans, dried cranberries, and crumbled goat cheese. Add the cooled sweet potatoes. Whisk the dressing once more and then drizzle over everything and stir gently to combine. You can garnish the top of the salad with a few more pecans, dried cranberries and goat cheese before serving. Enjoy!
