Clean cauliflower and break into large flowerette pieces. In a large piece of aluminum foil, tightly wrap cauliflower flowerettes and peeled garlic cloves that have been seasoned with salt and pepper and place in 350°F oven and bake for 45-55 minutes or until tender.
Put into casserole dish and mash to desired consistency (I like a little texture to mine). Add EVOO and cream and mix in well. Add the grated Romano cheese and season with salt and pepper as desired.
Can be made ahead and reheated in a 350°F oven until piping hot.
