Soak the Lentils: Place 1 1/4 cups (250 g) of dried lentils in a bowl and cover with water.. Allow them to soak overnight or for at least 8 hours. This softens the lentils and makes them easier to blend.
Preheat the Oven: Preheat your oven to 350°F (175°C). Line a rectangular baking mold (approximately 9x5 inches) with parchment paper or lightly grease it with oil.
Prepare the Lentil Mixture: Drain the soaked lentils and rinse them well. In a blender, combine the drained lentils, 2 tablespoons of Greek yogurt, 1 large egg, 1 teaspoon of olive oil, 1 teaspoon of salt, 2 teaspoons of baking powder and water. Blend until the mixture is smooth and well combined. The batter should be thick but pourable.
Add oat flour: Pour the contents of the blender into a mixing bowl. Add the oat flour on top and stir well to combine. Alternatively, you can do this step directly in the blender, but be aware that a very dense mixture might overheat the motor.
Pour and Top: Pour the batter into the prepared baking mold, spreading it evenly. Sprinkle the top with 1 tablespoon each of pumpkin seeds, almonds chopped, and whole oats. These add texture and a pleasant crunch to the bread.
Bake: Place the mold in the preheated oven and bake for 35-40 minutes, or until a toothpick inserted into the center comes out clean and the top is golden brown. If the top browns too quickly, cover it loosely with aluminum foil to prevent burning.
Cool: Once baked, remove the bread from the oven and let it cool in the mold for about 10 minutes. Carefully transfer the bread to a wire rack to cool completely before slicing.
