Bring water to a boil in a pot, boiling cauliflower in water with some salt and let it simmer until soft.
Preheat two nonstick pans over medium heat.
Preheat the oven to 175 degrees Celsius.
Toast the cumin and coriander seeds in a dry pan over medium heat until golden brown. Stir regularly. Keep the pan hot and add some olive oil.
Combine ingredients for the meatballs in a bowl. Form equally sized meatballs.
Add the meatballs to the other pan and fry until golden brown all around.
Place the meatballs in a oven safe dish and bake for 12-18 minutes, until done.
Meanwhile add all the ingredients for the chermoula to a blender and mix until smooth.
Taste to check if more seasoning is needed.
When the cauliflower is soft, remove it from the stow and drain well.
Using a hand mixer mix the cauliflower to a smooth purée. Add in the Creme Fraiche and season with sea salt, ground cumin and dijon mustard (if using).
Place the cauliflower on plates.
Add the meatballs on top when they are ready and top with chermoula and feta cheese.
