Bring a large pot of salted water to the boil. Add cauliflower and cook for three to 4 minutes, or until nearly tender. Remove with a slotted spoon or sieve. Drain and set aside in a bowl. Add potatoes and carrot to the boiling water and cook for about 4 minutes, or until just tender. Drain, then add potatoes and carrot to cauliflower.

In a small bowl, combine coriander, chillies, turmeric and 1 tablespoon peanut oil. Stir until well-combined.

Heat a wok or large frying pan over high heat, add 2 teaspoons oil and swirl around. Add green onions and stir-fry for about 1 minute, then add spinach and stir-fry until leaves are wilted. Remove from wok and set aside in a separate bowl.
