Preheat oven to 220ºC and line a 20 cm x 30 cm baking tray with baking paper.

Pulse cauliflower florets in a food processor until they resemble cauliflower rice.

Quarter fill a medium saucepan with water and bring to the boil. Place cauliflower rice into a sieve and steam for a few minutes until soft.

Use a large spoon to press out excess water from the cauliflower. Transfer cauliflower onto clean paper towel to drain remaining water.

Place cauliflower into a bowl with half the mozzarella, half the cheddar, eggs, mustard, paprika and a pinch of salt and combine well.

Spread mixture onto the baking tray, sprinkle with remaining cheeses on top and dust with a little extra paprika.

Bake for 20 to 25 minutes, until cheese is golden, and slice is cooked through. Cool slightly before slicing

Serve warm or cold.
