Combine pumpkin and oil in a large bowl and season to taste. Toss well to coat in oil. Place pumpkin on a baking paper lined tray. Cook in a preheated oven at 190°C for 25 minutes before adding sage leaves and cooking for a further 5 minutes until pumpkin is golden and sage is crisp.
Meanwhile cook pasta following packet directions. Drain and keep warm.
Heat Providore Series sauce in a saucepan and toss through hot pasta. Serve pasta and sauce topped with roasted pumpkin, sage leaves and a drizzle of extra olive oil. Garnish with parmesan.
Substitute sweet potato for the pumpkin, if desired.
