Wash the aubergine, cut into approx. 5mm thick slices, also cut the Wammerl into 5mm thick slices so that they cover the eggplant wheels well. The feta is also about 4 cm in size.
For one thaler you take 1 eggplant slice, place a piece of Wammerl on top and a piece of feta cheese on top. So 3 parts.
Finally a few needles of fresh rosemary.
Put the whole thing in a greased casserole dish, covering only the bottom. If you have a larger amount, it is best to use the baking sheet.
Bake at 180 degrees for about 20 minutes. If you like it crispy and brown, you can also grill it over.
