Preheat the oven to 375°F. Lightly coat a flat, unlined aluminum sheet pan with a thin layer of olive oil where the sweet potatoes will sit.
Cut the sweet potatoes in half lengthwise, leaving the skin on.
In a large bowl, coat the sweet potato halves with the olive oil, smoked paprika, garlic powder, salt and black pepper, making sure the cut sides are well coated.
Place the sweet potatoes cut-side down on the prepared baking sheet. Roast for 40–45 minutes, or until tender.
During the last 5 minutes of roasting, add the pine nuts to an open area of the baking sheet. Toast until lightly golden, keeping an eye on them so they don't burn.
Remove the pan from the oven and let the sweet potatoes rest cut-side down on the pan for 10 minutes. Carefully flip them over.
Top each serving with ½ cup cottage cheese, toasted pine nuts and microgreens. Add additional black pepper, if desired.
