Clean, wash and finely dice the peppers. Wash the tomatoes, cut off the lid. Hollow out the tomatoes, put the inside aside. Dice the lid and add half of the tomato inside.
Bring 200 ml of stock to the boil, add diced peppers and simmer for about 2 minutes. Stir in couscous, simmer for 2-3 minutes. Mix cream cheese and milk. Add the remaining tomato cubes to the couscous.
Cut the sausage into pieces, fold in. Season with salt, pepper and coriander. Stuff the tomatoes with it. Put the tomato interior and 125 ml broth into an ovenproof dish. Put the tomatoes in it. Cook in the preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: level 3) for about 15 minutes.
Coarsely crumble the chips and spread them on the tomatoes 5 minutes before the end of cooking time. Arrange on a plate and garnish with coriander green.
