Leave bacon cubes in a large pan without fat and turn until crispy. Meanwhile peel, wash and slice the potatoes and carrots
Add the potatoes to the bacon and fry covered for about 5 minutes. Shake the pan vigorously more often. Add the carrots, cover and fry for another 5 minutes.
In the meantime, clean the mushrooms, possibly halve them. Peel and chop the onion. Add both with the thyme to the pan and fry open for about 5 minutes. Season with salt and pepper
Remove the rind from the cheese slices, cut in half and place on the vegetables. Cover and let it melt for about 2 minutes. Garnish with herbs if necessary
