I made a Spinach Pie from this book, which I got for Christmas. The lovely "dinner ladies" used to make something similar at my beloved graduate school canteen, where it was my favorite choice.
Not only do I believe I'm getting a week's worth of iron in a slice, I feel like I'm making up for the dirty looks I gave my undergraduate college roommate when she offered to make Greek spanakopita for me. I'm eating it now, Janine, see? And I LOVE it.
