Put the water, oil, soy yoghurt, salt, brown sugar, dry yeast, baking powder and pepper in a large bowl and stir with a wooden spoon.
Then slowly but steadily add more and more spelled flour to the bowl, stirring continuously until it has a firm, non-sticky, but malleable consistency.
When this malleable consistency is reached, add a little spelled flour to the bottom of the bowl and let the dough rest for 45 minutes.
After resting, you can stir the chopped walnuts, flax seeds, sultanas, sunflower seeds and a chopped banana into the dough, then shape into small rolls with the help of a little spelled flour and place on the baking sheet.
Bake at 170 degrees until the rolls are golden brown.
