Preheat the oven to 205C [400F] and line a large rimmed baking sheet with parchment
Using a very sharp Chef's knife, cut a "lid" off the top of the squash or pumpkin- 3-4cm [1- 1¼ inch] deep
Set the lid aside and using a large spoon, scoop out the seeds and the stringy bits [discard]- clean the opening.
Drizzle one tablespoon of the olive oil over the inside of the pumpkins and sprinkle with about ⅛ teaspoon of salt- using a brush or your fingers, rub the oil/salt inside and especially along the cut rim. Turn the pumpkins over so the cut sides are against the parchment.
Bake until the squash flesh is easily pierced, about 15 - 18 minutes
Meanwhile, cook the quinoa. In a medium saucepan, combine the rinsed quinoa and the water. Bring to the boil over medium/medium high heat, then reduce to a gentle simmer and cook, uncovered until the water is absorbed- about 10 + minutes. Remove from the heat and stir in the cranberries. Cover for 5 minutes then remove the lid and fluff the quinoa mixture with a fork. Set aside to cool a bit.
Meanwhile, toast the pepitas [pumpkin seeds] in a dry, medium heavy bottom frying pan over medium high heat, shaking the pan frequently until they are going golden brown and starting to make popping sounds- about 4-5 minutes. Set aside to cool.
Tip the quinoa mixture into a large mixing bowl, and add the spring onion, chick peas [garbanzo] , garlic, ginger, parsley, coriander, remaining 1 tablespoon olive oil and lemon juice. Combine and add the pepitas, the parmesan and the feta and combine thoroughly. Add the remaining salt and cracked pepper to taste
Pop the squash halves over so the cut sides are facing up and divide the stuffing mixture into cavity and filling to the top [Note 2]. Garnish with pepita and minced coriander on top and return to the oven and bake for a further 15 + minutes
Remove from the oven and sprinkle with the reserved minced coriander. Place the baked stuffed pumpkin on a plate and serve with it's "lid" either on top or perched on the side.
