Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
Toss the cubed sweet potatoes with the extra virgin olive oil, ground cumin, smoked paprika, and half of the sea salt and black pepper.
Spread the sweet potatoes in a single layer on the baking sheet and roast for 20-25 minutes until they are tender and slightly caramelized.
Season the chicken breast with the remaining sea salt and black pepper, then grill or pan-sear over medium-high heat for 6-7 minutes per side until fully cooked.
While the chicken rests, warm the black beans in a small saucepan over medium heat until heated through.
In a small ramekin, whisk together the plain Greek yogurt and lime juice until smooth to create a light dressing.
Assemble the bowl by placing the baby spinach at the base, then topping with the roasted sweet potatoes, warm black beans, and the sliced chicken breast.
Drizzle the lime-yogurt sauce over the entire bowl and serve immediately while warm.
