Clean and wash spring onions and cut into fine rings. Put aside about 1 tbsp. for sprinkling. Clean and wash the chicory and cut in half lengthwise. Cut out the stalk in a wedge shape.
Heat the oil in a large coated pan. Fry the chicory halves in it for about 3 minutes. Season with salt and pepper and remove.
Fry the diced ham crisply in the frying fat. Take out approx. 2 tablespoons of diced ham to sprinkle over the top. Add spring onions to the pan and sauté briefly. Deglaze with tomatoes. Bring everything to the boil and simmer for about 5 minutes while stirring.
Season with salt, pepper and 1 pinch of sugar.
Roughly grate Gouda. Mix with cottage cheese. Pour tomato sauce into a large, flat casserole dish, add chicory. Spread cheese over it. Gratinate in a preheated oven (electric cooker: 225 °C/circulating air: 200 °C/gas: level 4) for 10-12 minutes.
Sprinkle with remaining spring onions and diced ham. Serve with rice.
