Spinach Pie at House of Fun (Athens)

My grandmother's traditional Greek Spinach Pie (aka Spa-na-KO-pee-ta), with crunchy flaky crust, tons of hot gushing spinach, greens, leeks and onions with a little crumbled feta cheese. Variations include sturdier, hard "shell-like" crust and more dense "cake-like" flour crust, depending on the occasion and who's making it. Love!
