Halve the chicory heads and cut off the hard ends. Rub the halves with 2 tablespoons of olive oil and lightly salt all around. Brush a baking dish with the remaining olive oil and place the chicory in it with the cut surface facing down. Place the mold in the oven preheated to 180 ° C for 20 minutes.
When the time has elapsed, turn the chicory halves over, add the cocktail tomatoes that have now been halved, drizzle with a little olive oil and lightly salt, and place in the oven for another 15 minutes.
In the meantime, put all the ingredients for the gremolata in a tall mixing beaker, puree and season with salt. Take the mold out of the oven and sprinkle generously with the gremolata.
Grainy cooked basmati rice is ideal as a side dish.
