Preheat oven to 375 degrees.
Oil a bread pan with avocado oil and set aside.
Grind sunflower and pumpkin seeds in the food processor until finely ground. Mix seeds with almond meal, coconut flour, arrowroot powder, baking soda, and salt until well combined.
In a separate bowl combine psyllium husk, ground chia seeds, and water and let stand 1 minute to thicken (don't let it stand longer as it will get too thick).
Add in apple cider vinegar, oil, and maple syrup (if desired).
Flour a cutting board with coconut flour. Combine wet ingredients with dry and mix with a spoon and then knead with your hands. Turn the dough onto a cutting board floured with coconut flour, and mix until combined well.
Add more coconut flour as needed until dough is not too sticky and then mold into the bread pan.
Bake for 65-70 minutes (I always do 70, but every oven is different). Let cool in the bread pan for 10 minutes and then take out and place on a rack to cool the rest of the way.
Slice and eat or freeze. Will last in the refrigerator approximately 3-5 days, and in the freezer for up to 6 months, but ours never lasts that long!
Eat as is or toast it and top with your favorite nut butter, avocado and sea salt, organic butter or ghee, hummus, or any other spreads or toppings you desire. Enjoy!
