Leek, Spinach, Lentil and Potato Pie

Who said pie has to always be sweet? No, I know, most of you like sweet pie. Hey, I like sweet pie (see the end of this post for more on that)! But I also love my veggies. This recipe PACKS in the veggies. Big time packs them in. That's why it has to have such a long name - because it just can't decide which veggie to promote the most (I know, lentils are technically pulses, but...potato potahto...)
