Chop the cauliflower into very fine pieces, then add to it the eggs, salt, pepper and chopped parsley and mix well. On a baking tray lined with baking paper make a disc with the cauliflower mix, and bake in the oven for 10 minutes at 180°C.
Once cooked, add a layer of tomato sauce on your cauliflower pizza base. Then add on top the oregano, ham, sliced mozzarella and black olives.
Bake in the oven for 15 minutes at 210°C. Garnish with fresh basil leaves and serve hot.
