Pan roasting vegetables is super simple. Just preheat your oven to 400 degrees. For easy clean up, line a rimmed baking sheet or large roasting pan with parchment paper. Cut your root vegetables into similar size pieces and place them in a large mixing bowl. In a small bowl, combine oil (olive or avocado) with chopped herbs of your choice, then drizzle over vegetables and give them a toss. Transfer vegetables in an even layer onto the lined sheet pan and place in the preheated oven. They're done when the natural sugars in the veggies begin to caramelize and they are fork tender.
