Begin by preheating your oven to 400°F (200°C) to create the perfect environment for roasting the sweet potatoes.
In a mixing bowl, combine the diced sweet potato with 1 tablespoon of olive oil, smoked paprika, garlic powder, cumin, salt, and pepper. Ensure the sweet potatoes are well coated with the seasoning mixture. Spread the seasoned sweet potatoes on a baking sheet in a single layer. Roast in the oven for 20-25 minutes, or until they are tender and beautifully caramelized.
While the sweet potatoes are roasting, prepare the brown rice. Rinse the rice thoroughly under cold water to remove excess starch. In a medium saucepan, combine the rinsed rice with the vegetable broth. Bring this mixture to a boil over medium-high heat. Once boiling, reduce the heat to low, cover the saucepan, and let it simmer for about 30-35 minutes, or until the rice is tender and all the broth has been absorbed.
As the rice cooks, place a skillet over medium-high heat and add the remaining tablespoon of olive oil. Season the chicken breasts with salt and pepper before placing them in the skillet. Cook the chicken for about 6-7 minutes on each side, or until each piece is fully cooked through and boasts a golden-brown exterior. After cooking, remove the chicken from the skillet and allow it to rest for a few minutes before slicing it into strips.
In the same skillet, without cleaning it, add the sliced bell pepper and zucchini. Sauté them for about 3-4 minutes, stirring frequently until they begin to soften and their vibrant colors come to life.
To create your delicious rice bowl, start by adding a generous base of fluffy brown rice to each serving bowl. Layer on the roasted sweet potatoes, followed by the sautéed bell pepper and zucchini, and finish with the sliced chicken on top.
For a fresh and vibrant touch, garnish each bowl with freshly chopped cilantro. Serve with lime wedges on the side, allowing everyone to squeeze a bit of lime juice over their bowl for an extra zing of flavor.
