Roasted Roots With Green Salsa

Ingredients
Method
Place a rack in lower third of oven; preheat to 450°. Place sweet potatoes, carrots, and scallions on a baking sheet. Drizzle a little oil over, season with salt and pepper, and toss to coat. Divide vegetables between 2 baking sheets if cramped and spread out into an even layer. Roast until tender and browned, 15–25 minutes.
Meanwhile, coarsely chop reserved carrot tops (you want about ½ cup) and place in a medium bowl. Add tomatillos, chiles, lime juice, and remaining 1 Tbsp. oil. Season salsa with salt and pepper and stir to combine (it will loosen as it sits).
Cut charred scallions into small pieces, add to salsa, and stir to combine. Divide sweet potatoes and carrots among plates and top with salsa and lots of cheese.
