We love quiches and I think I don't cook some too often! There are so many variations that I can't do twice the same one! Recently I've been using a lot of wheat bran in my breads, cakes, pancakes and quiche or tart doughs. It gives a fibery texture that I really love on top of being rich in nutrients. I simply add two large table spoon of wheat bran to the dough when kneading. For this very simple quiche with lotus root and shiitake I used also tried using okara in the egg base instead of tofu, which is also rich in fibers and protein and it gives a drier texture, a bit that of a fish cake that I really loved. So simple and delicious!
