In a large mixing bowl, combine the sweet potato cubes, olive oil, honey, ground cinnamon, and pinch of salt. Toss until coated.
Line a baking sheet with parchment paper, and spread the sweet potato cubes in a single layer.
Roast for 25-30 minutes, stirring halfway through until tender and golden.
Transfer to a serving dish and optionally sprinkle with freshly chopped parsley before serving.
