Place the cubed sweet potatoes in a medium bowl. Drizzle with olive oil, and season with salt, pepper, and half of the cumin and smoked paprika. Toss well to coat the sweet potatoes evenly.
Spread the seasoned sweet potatoes on a baking sheet lined with parchment paper in a single layer. Roast in the preheated oven for about 25-30 minutes, or until they are fork-tender and slightly caramelized, flipping them halfway through for even cooking.
While the sweet potatoes are roasting, in a large bowl, combine the cooked quinoa, black beans, corn, diced red onion, and diced bell pepper. Add the remaining cumin, smoked paprika, lime juice, and season with salt and pepper to taste. Mix well until all ingredients are thoroughly combined.
Once the sweet potatoes are done roasting, remove them from the oven and let them cool slightly. In individual serving bowls, layer the quinoa mixture first, and then top it with a generous portion of roasted sweet potatoes.
Garnish each bowl with slices of avocado and sprinkle chopped cilantro on top. If desired, add a dollop of Greek yogurt or dairy-free yogurt for extra creaminess.
Serve them as a wholesome lunch or dinner option, and enjoy the delightful flavors and textures!
Notes
Optional Greek yogurt or dairy-free yogurt can enhance creaminess.
