Peel and chop the onions, mix with the chopped garlic and some of the oil and place in a saucepan. Steam the onions until translucent. Divide the cauliflower into smaller florets and wash.
Peel the tomatoes, cut into cubes and add to the onion-oil mixture with the cauliflower florets. Fry them briefly and then pour a glass of water over them. Season with salt, freshly ground pepper, a pinch of nutmeg and a teaspoon of tomato paste. Stir and cook for about 5 minutes. Just before the end of the cooking time, add the freshly grated Parmesan and the remaining oil.
Baked potatoes, my lemon potatoes or even grainy rice and of course a crunchy salad taste great with it.
