Preheat your oven to 425°F and line two baking sheets with parchment paper.
After chopping all the vegetables, place them in a large bowl with the garlic and drizzle with avocado oil. Toss to coat the vegetables in oil, then add salt and black pepper. Stir again to evenly distribute the seasoning.
Spread the oiled and seasoned vegetables in a single layer evenly over the two lined baking sheets. Bake the two trays for 30 minutes, rotating at the halfway point.
After 30 minutes, remove the trays from the oven and evenly sprinkle the chopped herbs over all the vegetables. Stir around or toss vegetables on the baking sheet, then return to an even layer.
Return the baking sheets to the oven for 15-20 minutes until vegetables are fork-tender and caramelized.
Serve roasted vegetables warm with your favorite main dish.
