Preheat the broiler.
In a microwave-safe casserole dish, stir to combine cauliflower, soup, cayenne pepper, salt and shredded cheese. Cover with plastic wrap and microwave on high setting for 6 minutes.
In a small bowl, combine grated Parmesan, bread crumbs, and olive oil. Remove cauliflower from microwave and remove plastic wrap. Spoon bread crumb mixture over cauliflower and broil for 1 to 2 minutes until top is golden brown. Serve hot.
