1. Preheat your oven to 425°F. Line a baking sheet with parchment paper for easy cleanup.
2. In a large bowl, toss the sweet potatoes with olive oil, smoked paprika, cumin, chili powder, salt, and pepper until well coated.
3. Spread the sweet potatoes in a single layer on the prepared baking sheet. Roast in the oven for 25-30 minutes, or until tender and slightly caramelized, stirring halfway through.
4. While the sweet potatoes are roasting, prepare the rest of the ingredients. In a large skillet over medium heat, combine the black beans, corn, red bell pepper, and red onion. Cook for 5-7 minutes, stirring occasionally, until the vegetables are slightly softened.
5. In a small bowl, mix the diced avocado with lime juice and cilantro. Set aside.
6. Once the sweet potatoes are done, assemble your taco bowls. Start with a base of cooked brown rice or quinoa, top with the roasted sweet potatoes, black bean mixture, and avocado. Sprinkle with cheese if desired.
7. Serve immediately, garnished with additional cilantro and a squeeze of lime juice for an extra burst of flavor.

These bowls are not only a feast for the taste buds but also a joy to create. I always find that cooking, especially with my kids, turns into a mini adventure of its own, full of little lessons and lots of laughter.
