Peel the pumpkin and chop into smallish dice. Place in a roasting dish and sprinkle with a dash of oil (whatever you have on hand!) and bake at 200ºC until tender and browned around the edges.
Chop onion and coriander finely (I process in the processor!) and combine with any juice from the roasted pumpkin.
Nice at room temperature- nicer cold in a sandwich the following day (yes, I'm weird!)
