There are a wide variety of low-carb recipes. Well, this one is a bit more interesting variation of the classic German Onion Pie (Zwiebelkuchen). I borrowed the recipe from the German culinary site https://abnehmtricks-und-abnehmtipps.de, making some adjustments to my taste, such as replacing some products or their ratio. The site says that the low-carb version is better than the original. When I prepare the original, I’ll tell you 🙂
