I did feta and sour cherry mix here, must tell one of the best pastry filings I've tried so far.
Bright side is that glaze is liquid only for few hours, later it hardens, and therefore that unpleasant feeling of sweetness disappears. I wouldn't recommend glaze as filling, but with similar ingredients can be good combo.

that was quick:)
ah yes I remember!!
...well yes I was thinking to rather have some sort of chocolate-feta filling (without glaze)
Makes me think, recently I made some raw cheesecake (with cream cheese and yogurt) but there feta could be really tasty in it too then.
But oke Ill stop the ideas about feta here, get some and see where it gets me:)

Try melting chocolate, a bit of powdered sugar and feta all together (that should give salty caramel wanna be taste).

Okaaaay, your time to share!
Baking can't be harder than sewing. 😜

Oke I tried!
Feta, cream cheese and some peer, rolled in some tough... but I dont have an oven, so doing backing related things is super edgy every time... but kind of fun, Ill never know how it turns out😅
Tasted good but didnt look presentable..

Try to use bought crusts, or puff pastry.
Those can be prepared in pan.

Most important is that you enjoyed the taste, eyes can be closed. 😉
