Preheat your oven to 400°F and line a baking sheet with parchment paper for easy cleanup.
Peel and dice the sweet potato into 1/2-inch cubes, then spread them evenly across the prepared baking sheet.
Roast the sweet potato for 20 to 25 minutes, or until the cubes are tender and the edges are slightly caramelized.
While the potatoes roast, rinse and drain the black beans thoroughly and pat them dry with a clean kitchen towel.
In a small skillet over medium-low heat, combine the roasted sweet potatoes, black beans, maple syrup, and half of the ground cinnamon.
Stir the mixture gently for 2 to 3 minutes until the syrup has thickened into a light glaze that coats the beans and potatoes.
In a serving bowl, whisk together the non-fat Greek yogurt, vanilla extract, sea salt, and the remaining ground cinnamon until smooth.
Top the seasoned yogurt with the warm sweet potato and bean mixture, then finish by sprinkling the hemp seeds over the top.
