Put 2 tbsp coconut oil into a medium roasting pan and add the squash and shallots. Using your hands, turn the veggies over in the oil until they are thoroughly coated. Add the lemon zest and briefly toss the veggies again. Sprinkle over the sea salt and place the pan into the preheated oven for 20 mins.
Add the radishes, asparagus, and kale, toss again (using a couple of spoons this time!) and pop back into the oven for a further 20 mins, or until the kale is chip-crispy and the other veggies are bordering caramelized.
Meanwhile, cut the cauliflower into florets. In two separate batches, put them into a food processorr fitted with the 'S' blade and pulse until the cauliflower resembles large grains of rice.
Heat the remaining coconut oil in a skillet until very hot. Add the cauliflower rice and cook over a medium to high heat for around 3-4 mins until just tender, allowing it to char slightly.
Make the vinaigrette by simply putting all the ingredients into a small bowl and giving it a good whisk.
Put the cauliflower onto a serving platter and add the roasted veggies. Drizzle over the dressing, gently mix everything together and serve.
