Activate Yeast: In a large bowl, combine warm water, yeast, and honey. Let sit for 5-10 minutes until foamy.
- Mix Dry Ingredients: In another bowl, mix whole wheat flour, bread flour, oats, sunflower seeds, flaxseeds, chia seeds, sesame seeds, and salt.
- Combine and Knead: Add dry ingredients and olive oil to the yeast mixture. Stir until a dough forms, then knead on a floured surface for about 8-10 minutes until smooth and elastic.
- First Rise: Place dough in a greased bowl, cover, and let rise in a warm place until doubled in size, about 1 to 1.5 hours.
- Shape Loaf: Punch down dough, shape into a loaf, and place in a greased loaf pan. Sprinkle extra sunflower seeds on top.
- Second Rise: Cover and let the dough rise again for 30-45 minutes until puffy.
- Bake: Preheat oven to 375°F (190°C). Bake for 35-40 minutes, or until the bread is golden brown and sounds hollow when tapped.
- Cool and Serve: Remove from the pan and cool on a wire rack before slicing.
