Add the olive oil and half the butter to a large skillet over medium-high heat. When the butter is melted, add the onions and mushrooms. Cook until browned, about 8 minutes. Watch carefully so the onions don’t burn.
Add the cauliflower and water. Cook until the cauliflower is tender and browned, about 10-12 minutes.
Add the remaining butter, garlic and parsley to the skillet and stir. Cook until the butter is melted.
