Toss the cauliflower and romanesco in 1 tbsp of the olive oil, spread evenly on a baking tray and roast in the hot oven for 20 - 30 minutes until browned and just tender but still crunchy.
Meanwhile, in a large bowl, mix together spring onions, 1 tbsp olive oil, the ground coriander, a pinch of salt and some black pepper.
Add the cooked cauliflowers straight from the oven and the edamame beans, stir through and leave to cool.
Make the salsa by combining all the ingredients in a bowl.
Serve the cauliflower salad at room temperature topped with extra chopped coriander and small bowls of the salsa on the side.
