Potato and Leek Gratin
Healthy, because
Even smarter
The spicy gratin warms from the inside, makes you happy, and provides sufficient satiation. The essential oils of leek and spring onions give strength to the intestinal flora, which is very important for a good immune system. Leeks also have a diuretic effect, support kidney function, and provide immune-strengthening vitamin C.
To avoid the potato slices not being completely cooked after baking, they should be sliced as finely as possible. You can also pre-cook the potatoes the day before to make sure that the gratin has the right consistency.
