Preheat the oven to 400 degrees F.
In a large bowl, toss the broccoli, carrots and garlic with the olive oil, sesame seeds and some salt and pepper until fully combined. Transfer to an ungreased baking sheet. Roast until lightly brown and just tender, about 25 minutes. Drizzle with the Carrot Top Pesto.
Place the leaves and stems from the carrot tops in a food processor with the parsley leaves, roasted cashews and garlic. Puree and then slowly drizzle in the extra-virgin olive oil while the machine is running. Add the grated Parmesan and kosher salt to taste. Puree until combined.
