Preheat the oven to 425 degrees F and line a baking sheet with parchment. Place the carrots on the baking sheet, drizzle lightly with olive oil, and sprinkle with salt and pepper. Roast for 15 to 25 minutes, or until browned and soft. The time will depend on the thickness of the carrots.
Remove the carrots from the oven, let cool slightly, then chop and transfer to a small food processor. Add the olive oil, tofu, miso paste, rice vinegar, ginger, garlic, sesame oil, and sriracha and pulse to combine. the carrots should be fairly well pureed, and the mixture will be thick. Stir in the scallions.
