Place the walnuts, chia seeds, sunflower seeds, pumpkin seeds and sesame seeds in a food processor or high-speed blender and blend until a flour forms.
Place the flour in a big mixing bowl and add the baking powder and the salt.
Add the eggs and the water. And mix it well to combine all the ingredients.
Preheat the oven to 180°C/360°F and grease a loaf tin with coconut or olive oil.
Spoon the mixture into the tin, and press it down firmly using a spoon.
Sprinkle the loaf with any leftover seeds(optional)
Bake the bread for 45-50 minutes, until the top starts to brown and a toothpick inserted comes out clean.
Remove from the oven and let cool completely while still in the loaf tin.
Once cooled cut slices and enjoy them with your favorite toppings.
