I loved the one from Dorie pre-Gateau too, where she says you can use up any stubs of cheese you have sitting around.
I am also thinking they might enjoy the slightly spiced / Indianized one from Chetna (from The Cardamom Trail) – spinach and ricotta, reminiscent of palak paneer – I might add garlic butter.
I am nothing if not repetitive, I realize more and more – but I scrolled down and saw your Manchego and Chorizo bread link, which sounds really good.
