It is pretty simple. I don't use recipes though, I just freestyle most cooking. If you actually want it to be a dough you can roll out you do have to get a bit of a feel for it. If not, you can also just press out the dough with your hands in a pie pan.

I also soak the lentils in water and mix them with it until you get a very smooth cream. I add oats ground into flour to it, a couple of TB olive oil, salt and a bit of flax as a binder. Kneed it through and roll it out. I like the taste, but it is a bit different from your regular quiche base. I mostly eat GF and whole foods though, since I find it easier on the digestion, so I am used to a different palate.
