Combine yeast and warm water (110 to 115 degrees) in a stand mixer bowl and let proof for about 5 minutes.
Mix the cottage cheese, honey, sugar, egg, oil and salt together in a saucepan and warm gently just to remove any chill, then add to the mixing bowl with the proofed yeast.
Add 2 cups of bread flour. Set the bowl on the mixer stand and beat with either the paddle or the dough hook for 2 minutes. Add the whole-wheat flour, wheat germ, rye flour and oats.
Knead dough with dough hook for about 8 minutes, stopping to scrape sides as needed, until smooth and elastic, adding additional bread flour if needed. The dough should cling to the hook. It may still stick to the sides a bit, but will snap off and be easy to handle.
Place in a greased bowl; cover and let rise for one hour or until doubled in bulk. Alternatively, you can just scrape the dough into the center of the stand mixer bowl, cover and let rise.
Punch dough down. Shape into one round loaf and place on a piece of parchment paper or shape into two rounds.
Cover with greased plastic wrap and let dough rise again for about 45 minutes. Don't overproof it.
Meanwhile, preheat the oven along with a Dutch oven to 400 degrees F. If baking without a Dutch oven, preheat to 350F.
Brush the risen loaf or loaves with egg white and sprinkle outside with pumpkin seeds and whatever other seeds you feel like using.
Remove Dutch oven from oven and lift the parchment paper with the loaf up and into the hot Dutch oven. Close. If using a baking sheet and making two loaves, give them plenty of space, but they should both fit on one large sheet.
For the Dutch oven, bake covered at 400 degrees for 30 minutes, then uncover and bake at 350F for 15 to 18 minutes. If baking without Dutch oven, bake at 350 for about 45 minutes. Internal temperature should be between 200 and 205. The seeds should not burn, but you can check occasionally and shield with foil if your seeds are browning.
Let cool completely before slicing for sturdier bread. If you cut it while warm it will be soft and less sturdy.
