Pierce each sweet potato several times with a fork and place them on a baking sheet. Roast in the preheated oven for about 45-60 minutes, or until tender.
While the sweet potatoes are baking, prepare the quinoa. In a medium saucepan, combine quinoa and vegetable broth (or water). Bring to a boil, then reduce heat to low, cover, and let it simmer for about 15 minutes, or until the quinoa is fluffy and the liquid is absorbed.
In a large mixing bowl, combine the cooked quinoa, black beans, diced bell pepper, corn, cumin, smoked paprika, salt, and black pepper. Mix until all ingredients are well incorporated.
Once the sweet potatoes are cooked, let them cool slightly before slicing them in half lengthwise. Scoop out a small portion of the flesh and mix it into the quinoa mixture to enhance the flavors.
Stuff each sweet potato half generously with the quinoa mixture, pressing down slightly to fit it all in.
Top each stuffed sweet potato with diced avocado and sprinkle with fresh cilantro.
Serve with lime wedges on the side for a zesty kick.
