1. Add the flour, oat flakes (or spelt flakes), sunflower seeds, flaxseeds, sesame seeds, dry yeast, and salt to a large bowl and mix to combine. Add yogurt, olive oil, and water, and knead until you get a well-mixed dough. If it looks too dry, add some more water. If it is too sticky, add some more flour and continue kneading. The dough should be slightly moist but not stick to the bowl.

2. Preheat the oven to 50°C (120°F), turn it off, and place the covered bowl with the dough inside. Let it rise for 60-90 minutes until the volume of the dough has almost doubled. Line a baking sheet with baking parchment and set aside. Divide the risen dough into six equal portions and shape into balls. Add the mixed seeds to a small bowl and press the dough balls into the mix, then place them on the baking sheet with some space in between. Use a sharp knife and cut a cross into each ball, cover, and let rise another 25-30 minutes.

3. While the dough is rising once more, preheat the oven to 180°C (350°F). Place a small heat-resistant bowl with water in the oven. Place the baking sheet in the oven and bake the bread rolls for about 20 minutes – the rolls should have some color and sound hollow when you tap the bottom with your fingers. Take them out of the oven and let them cool down.
