"This recipe is my favorite for a good healthy bread. Especially because it is so quick and there is no need to let it rise.
I love to make it for breakfast or brunch or as a present. It takes 10 minutes and 1 hour in the oven, so you can prepare breakfast and take a shower while you wait."
Combine water and yeast in a bowl; stir until yeast is dissolved. Stir in vinegar, salt, and honey.
Combine all-purpose flour, rye flour, walnuts, 1/3 cup sunflower seeds, and 1/3 cup pumpkin seeds in a large bowl. Stir in water mixture with a wooden spoon until dough is sticky and soft. Transfer dough to the prepared loaf pan. Sprinkle 1 tablespoon pumpkin seeds and 1 tablespoon sunflower seeds on top.
Place loaf pan in the cold oven. Heat oven to 400 degrees F (200 degrees C). Bake until top is golden brown, about 1 hour.
