1: Prepare 200 g turnip (or other vegetable) tops (See these tips) then cook them into a pan over medium heat with 20 g butter (The frenchs said "faire tomber"). Set aside.
2: Preheat your oven to 200°C (390°F). Prepare 300 g cauliflower, put it in a bowl, sprinkle it with 4 tablespoons olive oil, salt, pepper and mix well.
9: And finish with 100 g cheese, which you will grate or cut into strips depending on what you have on hand (here 2 leftover cheeses, Comté and Brie).
10: Bake for 30 to 40 minutes.
Remarks
The proportions of tops, cauliflower and potatoes are indicative, make with what you have on hand. For the cheese, it is interesting to put several different ones, for example leftovers, even a little dry, which can be used without waste.
