1
Preheat the oven to 400F/200C. Add all the vegetables to a baking sheet, drizzle with olive oil and sprinkle with fresh thyme leaves, salt and pepper. Roast for 30 to 35 minutes, or until the vegetables are fork tender.
2
Transfer the vegetables to a food processor, along with the other ingredients. Process until you obtain a creamy texture. A little bit of hot water or plant milk can help with consistency if it's needed.

Transfer the mash to a serving platter, garnish with fresh herbs, extra virgin olive oil and (optionally) a pinch of grated tonka beans. Tonka beans have an incredible flavor. If you can't find them, grate some nutmeg instead.
