Preheat your oven to 400°F (200°C). This temperature is perfect for roasting the sweet potatoes until they are tender and caramelized.
Peel and dice the medium sweet potato into 3/4-inch cubes. In a mixing bowl, toss the diced sweet potatoes with olive oil, onion powder, garlic powder, ground cumin, smoked paprika, and salt.
Spread the seasoned sweet potatoes evenly on a sheet pan. Make sure they are in a single layer for even roasting.
Place the sheet pan in the preheated oven and roast for about 20 minutes. Toss halfway through to ensure even cooking.
After 20 minutes, remove the pan from the oven. Add the drained and rinsed black beans and the shredded kale to the sheet pan. Toss everything together and return it to the oven for an additional 10-15 minutes, or until the kale is wilted and the sweet potatoes are fork-tender.
While the hash is roasting, poach your eggs. You can do this in a pot of simmering water for about 3-4 minutes, or until the whites are set but the yolks remain runny.
Remove the sheet pan from the oven. Season with freshly ground black pepper and additional salt if desired. Serve the hash warm, topped with sliced avocado, a poached egg, and your favorite salsa.
