Transfer the cauliflower to a microwave-safe dish or bowl. Cover and cook in the microwave for 10 minutes. Alternatively, you can steam the cauliflower in a steamer basket, or bake it in the oven at 375 degrees F fr 20 minutes.

When the cauliflower is cool, transfer it to a bowl lined with a kitchen towel or cheesecloth. Bring the ends of the cloth together and squeeze as much liquid out of the cauliflower as you can. Transfer the cauliflower to a mixing bowl and add the eggs,1/2 cup cheese, Italian seasoning, salt , and pepper. Mix to combine.

Transfer the mixture to a baking sheet lined with parchment paper. Form the dough into a rectangle about 8 x 12 inches and 1/4-inch thick. Bake in the oven for 15-20 minutes until cooked. Remove the baking sheet and sprinkle the remaining 1/2 cup cheese over the top. Bake for another 5-10 minutes, until cheese is melted.
