Preheat oven to 400 degrees. Line a baking sheet (round or rectangle) with parchment paper.
2. Place frozen cauliflower in a microwave-safe bowl. Microwave for about 2 minutes until the cauliflower has started to defrost. Pat the top of the cauliflower with a paper towel to remove excess moisture.
3. Add goat cheese to the cauliflower and microwave for an additional 30 seconds. Add egg, seasoning, and salt. Stir until well combined. The mixture will seem a little soft and wet. If you don't have garlic and herd goat cheese, you can use plain goat cheese and add an extra tsp of the Italian seasoning.
4. Pour the mixture out onto the parchment paper and flatten into a circle (or whatever shape you like, really) about 10-11 inches in diameter, and 1/2 inch thick.
5. Bake for 40 minutes, rotating the tray halfway through baking time to ensure even color. Baked crust will be a dark, golden brown and the edges will be crispy. Top with sauce, cheese, and whatever else you fancy and bake for 5-10 minutes until the cheese melts and browns very slightly on top.
