Preheat oven to 400 degrees.
Place the cubed sweet potatoes on a baking sheet. Drizzle with the olive oil and sprinkle the smoked paprika, cumin, garlic powder and salt. Toss to coat all of the cubed pieces and spread out in a single layer. Roast in the oven for 20-25 minutes until easily pierced with a fork. Set aside to cool.
Meanwhile place the salad greens in a large bowl.
Add the black beans, corn, red pepper and onion. Add the sweet potatoes once cooled.
Top with the pepitas and any other desired toppings. Serve with a side of the creamy cilantro lime vinaigrette.
