Preheat the oven to 425F.
Cut the sweet potato into ½-inch cubes and toss lightly in olive oil and salt.
Spread the sweet potato cubes on a baking sheet and bake at 420F for 20-25 minutes until the cubes begin to turn slightly brown at the edges.
While the sweet potato is baking, prepare the other ingredients if not already done.
Prepare the vinaigrette by adding the balsamic vinegar, olive oil, Dijon mustard, honey, salt, and pepper to a bowl. Whisk until combined.
In a large salad bowl, toss the kale and optional wild rice. Add the sweet potato, apple, goat cheese, and chicken. Top with 2-3 tbsp vinaigrette.
