Preheat oven to 375F.
In a small blender with grind attachment, food processor or a spice grinder, add lentils and grind to a flour. (I use my Magic Bullet with the flat blade).
Add the coconut oil (or oil/butter of choice) to a 8x8 or 9x9 pan* and let melt in the oven and warm (about 2 minutes). Meanwhile, add flaxseed meal, water and salt to ground lentils and blend again for about 15 seconds. It should resemble a thick but pourable pancake batter after it sits (the flax and lentils will start absorbing the water the longer it sits).
When oil is hot and melted, pour batter into the pan and spread with a spatula. Bake for 25-30 minutes until the bread forms a crust. Let cool slightly, cut and enjoy warm!
