Heat the oil in your deep fryer to 350 degrees F. Preheat the oven to 200 degrees F. Place the flour and egg/milk mixture in separate, large bowls. Place the breadcrumbs, herbs, salt and pepper in a third bowl. Coat the cauliflower florets in the flour, and then thoroughly coat in the egg mixture. Now coat the cauliflower in the breadcrumb mixture. Deep-fry, in batches, until golden and just tender, about 3 to 4 minutes. Drain well and arrange on a heatproof serving platter. Keep the cooked cauliflower warm in the oven as you deep-fry the next batch. When all the cauliflower is cooked, sprinkle with the Parmesan cheese and parsley and serve.
