Preheat the oven to 180C/356F/gas mark 4.
Line a baking tray with parchment paper and grease with olive oil then set aside.
Chop the cho cho into chunks (you can leave the skin on, if it has no brown spots).
Place the chopped cho cho on the tray, spread out and coat the top with olive oil.
Roast the cho cho for 40 minutes or until lightly golden.
Remove the tray from the oven and set aside.
Add the olive oil on medium heat in a medium sized saucepan.
Saute the onion, garlic and ginger until soft and translucent.
Add the chadon beni, thyme, scotch bonnet and the roasted cho cho and mix to combine.
Pour in the vegetable broth and coconut milk.
Reduce the heat to medium-low and simmer for 5 minutes.
After the given time, transfer the contents of the soup into a blender (or you can use an immersion stick instead).
Do a taste test and add black pepper and pink salt to taste.
