Pre-heat the oven to 400°F (200°C).
Wash and peel the carrots and parsnips. Cut them into small strips. Peel and cube the pumpkin.
Place all the vegetables into a roasting tray, and grease evenly with 1 tbsp. of olive oil. Season with salt and pepper, and roast in the oven for 20-30 minutes (depending on the thickness of the vegetables).
Once cooked add the roasted vegetables and rocket to a large bowl and drizzle with the remaining 1 tbsp. of olive oil.
Sprinkle with crumbled feta cheese and pumpkin seeds, and season with salt and pepper to serve.
