Place cauliflower in a food processor and blitz until it resembles fine breadcrumbs. You may have to do this in two batches.
Place cauliflower into a clean tea towel and squeeze out as much liquid as possible. Place into a large bowl, add eggs, parmesan, herbs and season with salt and pepper. Mix well with a spoon or hands work well.
Line an oven tray with baking paper. Place all the cauliflower mix onto the paper and push it out into a large circle 30cm in diameter x 1cm thick. Pat it down to compress. Place into the middle of the hot oven for 20 minutes until golden brown.
Once the base is cooked, cover it with your favourite toppings and then return to the oven until your toppings are cooked.
