Grate the head of cauliflower with a box grater or finely chop it in a food processor. (You should have about 3½ cups.) Place the cauliflower in the center of a clean kitchen towel and twist it firmly to squeeze out all the water. (This can be done in two batches to make it easier to drain all the water from the cauliflower.) Place the cauliflower in a large bowl and add the eggs, flour, Parmesan cheese, salt and pepper. Combine well.

Pre-heat the air fryer to 400°F.

Shape little patties out of the cauliflower mixture, using roughly 2 tablespoons at a time. Place the patties in a single layer into the air fryer basket and spritz with oil. Air-fry in batches: 8 minutes on one side, flip over and then air-fry for an additional 2 minutes.

To make the pepperoni pizza bites, flip the cauliflower crusts back over and top with pizza sauce, mozzarella cheese and mini pepperoni slices. Air-fry at 360°F for 3 to 5 minutes, until the cheese has melted. Let the bites rest for a few minutes before serving with a sprinkling of oregano on top.

To make the goat cheese & olive pizza bites, flip the crusts back over and brush the crusts with some olive oil. Top with the goat cheese and black olives. Air-fry at 360°F for 3 to 5 minutes until the cheese has melted. Transfer the pizza bites to a platter and then sprinkle with the lemon zest, chopped rosemary and freshly ground black pepper.
