Soak the chickpeas overnight in double the volume cold water
Preheat the oven to 200 degrees C
Cut the butternut or pumpkin 2cm chunks
Place on a roasting tray, drizzle with olive oil, season with sea salt and roast for about 30 minutes until the pumpkin is cooked and caramelised around the edges
Remove from the oven and leave to cool.
When cool, place the pumpkin pieces in a food processor with all the remaining ingredients, except the baking powder and chickpea flour
Blitz until just combined (not mushy or pasty)
Check the seasoning and place the mixture in a bowl
Add the baking powder and chickpea flour and mix until combined and place in the fridge for at least an hour
While the mixture chills make the whipped feta dip by placing all the ingredients in the food processor and pulse until well combined
Heat the oil in a medium sized saucepan (to reach at least 5cm up the sides of the pan) and test if the oil is hot enough by dropping a small bit of mixture into the oil. The mixture must start to sizzle and fry immediately.
Wet your hands and press the mixture into balls about the size of a walnut.
Fry in the oil in batches for 6 - 8 minutes until well browned and cooked through
Drain and serve while hot
