Step 1: Preheat your oven to 400°F (200°C). Line a large baking sheet with parchment paper for easy cleanup.
Step 2: In a large bowl, toss the diced sweet potatoes with 1 tablespoon olive oil, smoked paprika, chili powder, garlic powder, salt, and pepper until evenly coated.
Step 3: Spread the seasoned sweet potatoes in a single layer on the prepared baking sheet. Roast for 20-25 minutes, flipping halfway through, until tender and slightly caramelized.
Step 4: While the sweet potatoes are roasting, prepare the black beans. In a medium saucepan, combine the rinsed and drained black beans with 1/4 cup water, chopped red onion, and half of the chopped cilantro. Simmer over medium heat for 5-7 minutes, stirring occasionally, until heated through and slightly thickened. Season with a pinch of salt and pepper.
Step 5: Prepare the lime dressing. In a small bowl, whisk together 3 tablespoons olive oil, fresh lime juice, maple syrup (or honey), ground cumin, salt, and pepper until well combined.
Step 6: Assemble the power bowls. Divide cooked brown rice or quinoa (if using) among four serving bowls. Top with roasted sweet potatoes, seasoned black beans, and diced avocado.
Step 7: Drizzle generously with the lime dressing. Garnish with the remaining fresh cilantro. Serve warm and enjoy these wholesome sweet potato recipes healthy!
