Preheat the oven to 475°F. Line a sheet pan with aluminum foil. Pat the chicken wings dry with paper towels and place on the prepared sheet pan. Drizzle with oil and season with salt and pepper; toss to thoroughly coat. Arrange in a single layer. Roast 22 to 24 minutes, or until lightly browned and cooked through. Leaving the oven on, remove the roasted chicken wings from the oven. Leaving the foil on the sheet pan, carefully transfer the chicken wings to a large bowl.
While the chicken wings roast, wash and dry the fresh produce. Cut the sweet potato lengthwise into 8 equal-sized wedges. Cut out and discard the cabbage core; thinly slice the leaves. Peel the carrot and grate on the large side of a box grater. Cut off and discard the root ends of the scallions; thinly slice, separating the white bottoms and green tops.
While the chicken wings continue to roast, line a separate sheet pan with aluminum foil. Place the sweet potato on the prepared sheet pan. Drizzle with olive oil and season with salt and pepper; toss to thoroughly coat. Arrange in a single, even layer. Roast, turning halfway through, 13 to 15 minutes, or until browned and tender when pierced with a fork. Leaving the oven on, remove the roasted sweet potato from the oven.
While the sweet potato roasts, in a medium bowl, combine the cabbage, carrot, white bottoms of the scallions, sugar, mayonnaise, and half the vinegar; season with salt and pepper. Set aside to marinate, stirring occasionally, for at least 10 minutes. Season with salt and pepper to taste.
While the slaw marinates, in a bowl, whisk together the molasses, ketchup, mustard, and remaining vinegar. Season with salt and pepper to taste.
Add half the glaze to the bowl of roasted chicken wings; toss to thoroughly coat. Reserving the bowl, return the wings to the prepared sheet pan in a single layer. Roast 3 to 5 minutes, or until heated through. Remove from the oven and carefully return to the bowl. Add the remaining glaze; carefully toss to coat. Divide the glazed wings and roasted sweet potato between 2 dishes. Garnish with the green tops of the scallions. Serve with the slaw on the side. Enjoy!
