Sounds really good! Yea, I would skip the pastry or get store bought lol, I am not into making pastry, even when I did a ton of cooking, I wasn't into making pastry very often! Probably skip the shell!
There was one recipe I used to have to make pastry for and it called for making little fold over tarts with a asparagus, mushroom and mustard sauce stuffing, I haven't made those for years and would have to wing it if I tried to again. But that would mean pastry making and it's not going to happen! Hmm, although you can buy little vegan pastry squares nowadays.
But I remember I used to love quiche...............I think I had barely had it for the first few times and then I stopped eating eggs!
