Preheat the oven to 180°C (350°F). Line a small baking tray with plastic-free baking parchment.
Place the beetroot in a large bowl, drizzle with 1 tablespoon of the olive oil, sprinkle with salt and toss to coat well. Spread evenly on the prepared tray and roast for 45-60 minutes, or until tender. Set aside to cool.
Transfer the beetroot to a food processor with the remaining 2 tablespoons of olive oil, chickpeas, garlic, lemon juice, tahini and process until thick and smooth. With the processor still running add 2 to 3 tablespoons of water until you reach the perfect creamy consistency
Transfer to a serving bowl, drizzle with extra olive oil and sprinkle with sesame seeds and pine nuts to serve.
