Preheat the oven to 400ºF.
Place the sweet potatoes on a baking sheet and prick them with a fork.
Bake sweet potatoes for 40 minutes or until fork tender, then let rest for 5 minutes.
While potatoes bake, heat olive oil in a large skillet over medium heat.
Add chopped red onion and bell pepper and sauté until tender, about 5 minutes.
Add frozen corn, cooked quinoa, black beans, chili powder, cumin, smoked paprika, and sea salt to the skillet; cook for 2 to 3 minutes, stirring to combine.
Slice the baked sweet potatoes in half and place each half on a plate.
Top each sweet potato half with the quinoa mixture and mashed avocado.
Drizzle with tahini and hot sauce, then sprinkle with chopped cilantro before serving.
