Preheat the oven to 350°F. Line an 8.5 x 4.5 inch loaf pan with parchment paper, leaving some overhang on the long sides.
Blend the cottage cheese, eggs, olive oil and apple cider vinegar in a blender until completely smooth.
In a large bowl, whisk together the almond flour, ground flaxseed, psyllium husk powder, baking powder and sea salt.
Pour the blended mixture into the dry ingredients and stir until a thick batter forms. Fold in 3 tbsp sunflower seeds, 3 tbsp pumpkin seeds and the chia seeds, then let the batter rest for 5 minutes to thicken.
Scrape the batter into the prepared pan and smooth the top with a damp spatula. Sprinkle the topping seeds evenly over the surface and press them in lightly so they stick.
Bake for 50 to 55 minutes, until the top is golden brown and a toothpick inserted in the center comes out clean.
Cool in the pan for 15 minutes, then lift the loaf out and cool completely on a wire rack before slicing.
