Boil the cauliflower for 10 minutes until tender. Drain and set aside.
Preheat the oven to 350F.
Heat the oil in a large skillet (12" at least). Add the onion and saute for about 5 minutes.
Add the garlic and cook for one minute more, then add the rice and stir to combine. Saute all this for another 2 minutes or so.
Add the broth and bring to a boil.
Stir in the cauliflower and cheese and cover the skillet with a lid and bake in the oven for 25 minutes until all liquid has absorbed.
Remove from the oven and let sit for 5 minutes before uncovering.
Sprinkle the bread crumbs and drizzle the top with olive oil and bake until the breadcrumbs are toasted, or just stick it under the broiler for 5 minutes.
Serve in bowls with lots of cracked pepper!
