Cut the cauliflower florets off the stem and put them into a food processor. Depending on the size of your processor, you may need to do this in a couple of batches. Chop the cauliflower until they resemble grains of rice.
Place the chopped cauliflower into a microwave-safe bowl and microwave for 6 minutes.
Preheat your oven to 200C/390F.
Line a strainer with a cheesecloth. Add the microwaved cauliflower inside the cheesecloth. The cauliflower is actually really hot so what I like to do is pass the hot cauliflower pieces under the cold water inside the cheesecloth inside the strainer so no pieces go away. This cools down the grains.
Squeeze all of the water out as tightly as you can with the cheesecloth.
Transfer the grains to a large bowl. Add the goat cheese, eggs, flour, salt and pepper, and chopped parsley. Mix together with a fork making sure the goat cheese is mixed in well with the cauliflower.
Line 2 baking trays with parchment paper.
Separate the "dough" into 2 portions. Place the dough on the tray and shape into a 25cm/10in circle. Make sure the dough is flat everywhere. Repeat this with the second dough on the second tray.
Bake in oven for 20 minutes. Do not turn off the oven. Set the oven to 230C/450F.
