Place pumpkin, chickpeas, garlic, cumin, coriander, 1 tablespoon olive oil, lemon juice and sea salt in the bowl of a food processor and process until smooth.
Taste and adjust seasonings with extra salt if needed.
Heat remaining oil in a small frying pan and add pumpkin seeds, chilli, cumin, coriander and a sprinkle of sea salt. Cook, stirring until seeds start to change colour.
Remove from heat and arrange pan contents over the top of the hummus.
