Preheat your oven to 400°F (200°C).
Peel and cube the sweet potato into half-inch pieces.
On a parchment-lined baking sheet, toss the sweet potato cubes with olive oil, sea salt, black pepper, and smoked paprika.
Roast the sweet potatoes for 20 minutes or until they are fork-tender and slightly caramelized.
Transfer the roasted potatoes into a small oven-safe skillet or baking dish.
Stir in the rinsed black beans to distribute them evenly among the potatoes.
Pour the liquid egg whites over the potato and bean mixture.
Carefully crack the two whole eggs on top, keeping the yolks intact.
Return the dish to the oven and bake for 10 to 12 minutes, or until the egg whites are fully opaque and the yolks reach your desired consistency.
Sprinkle with chopped fresh chives before serving hot.
