Sear the minced meat with the diced onions and chop, season with salt and pepper.
When the meat is well browned, deglaze with the vegetable stock.
Add the leek cut into approx. 0.5 cm thick slices (including the greens) with the processed cheese, season with spices and simmer for a good 3/4 hour, stirring again and again in between. Add garlic to taste.
The soup tastes best the next day when it is warmed up
