Bring 100 ml water and a little salt to the boil in a small pot. Add rice and let it swell for about 12 minutes at low heat in a closed pot. Cut the fennel bulb into thin slices or wedges (put fresh fennel green aside). Steam vegetables covered in boiling salted water for about 10 minutes. Cut tomatoes into quarters, remove seeds as desired. Dice flesh finely. Heat the oil in a small coated pan and fry the steak for 8-10 minutes while turning.
Season with salt and pepper. Wrap in aluminium foil and let it rest for about 5 minutes until the meat juice has settled. Briefly sauté the diced tomatoes and shallots in the cooking fat. Add rice and braise for a few minutes, turning several times. Chop the fennel greens and mix in. Season to taste with salt and pepper. Arrange steak with tomato rice and fennel vegetables
