Clean, wash and slice the carrots and mushrooms. Peel the onion and cut into small cubes with the bacon.
Heat the margarine in a pan and fry the diced bacon and onion in it. Add the carrot and mushroom slices, pour in the wine and cook everything over low heat for about 15-20 minutes. Season to taste with salt, pepper and sugar. Wash and chop the parsley and sprinkle over the vegetables. Drizzle with lemon juice and serve.
TIP: Mushroom and carrot stew, served hot and cold, goes well with roasted pork
