In a heavy base saucepan heat the oil on a medium heat and then add the onion and fry for 2-3 min until it begins to soften and become opaque. Add in the chicken and fry for 3mins until it starts to brown. Add in the pumpkin, capsicum and curry paste. Cook for 2 mins until curry paste becomes fragrant. Then add in coconut cream. Bring to the boil and then reduce to a simmer for 20min or until pumpkin is cooked through. This is the stage that you can freeze the curry, and add your fresh greens when you reheat it!
