Preheat your oven to 400°F and line a baking sheet with parchment paper.
Toss the cubed sweet potatoes and sliced chicken breast with olive oil, sea salt, cumin, and chili powder until evenly coated.
Spread the chicken and potatoes in a single layer on the baking sheet and roast for 20 minutes until the chicken is cooked through and potatoes are golden.
While the tray roasts, lightly sauté the cauliflower rice in a non-stick skillet over medium heat for 5 minutes until tender.
Warm the black beans in a small saucepan or microwave until heated through.
Build your bowl by placing the cauliflower rice at the base, then topping with roasted chicken, sweet potatoes, and black beans.
Garnish with fresh avocado slices, chopped cilantro, and a bright squeeze of lime juice before serving.
