Preheat oven to 425 degrees or 400 degrees on convection. Line a rimmed baking sheet with unbleached parchment paper. Place carrots on baking sheet and toss with oil. Season with salt. Roast the carrots for about 20 minutes or until slightly golden brown.
In a small bowl, whisk honey and sriracha until well combined. Remove the carrots from the oven and brush with honey mixture. Continue to roast carrots for 10-15 minutes, or until caramelized.
Place the carrots on a large platter. Top with crumbled feta and a drizzle of honey, if desired. Sprinkle the pistachios and herbs on top of the carrots.
