Preheat your oven to 400°F (200°C).
Peel and cube the sweet potato into 1/2-inch pieces.
Toss the sweet potato cubes with 0.5 tsp of olive oil and a pinch of the salt, pepper, and smoked paprika.
Spread the sweet potatoes on a parchment-lined baking sheet and roast for 20-25 minutes until tender and slightly caramelized.
While potatoes roast, season the chicken breast with the remaining garlic powder, smoked paprika, salt, and pepper.
Heat the remaining 0.5 tsp of olive oil in a skillet over medium-high heat.
Sear the chicken for 6-7 minutes per side until the internal temperature reaches 165°F.
Remove the chicken from the pan and let it rest for 5 minutes before slicing into strips.
In the same skillet, sauté the sliced red and green bell peppers for 3-5 minutes until they are crisp-tender.
Assemble your bowl by placing the cooked brown rice at the base, followed by the sliced chicken, roasted sweet potatoes, and sautéed peppers.
