In a large bowl, crack the egg, add the salt, and beat lightly with a whisk or fork.

Pour in the rice flour and mix well.

Add the cornmeal to the bowl and mix well again.

Add the baking powder and mix again.

Gradually pour in the kefir and stir until smooth.

The dough should be smooth and lump-free.

Now pour in the flaxseed flour and mix.

Add the flax and sunflower seeds.

Pour in the oil and mix all the ingredients well. The dough should have a medium consistency, not too runny, but not too thick either.

Carefully pour the prepared batter into the silicone baking pan.

Sprinkle sunflower seeds or sesame seeds on top, if desired, and cut along the top with a knife.

Place the pan with the dough in the oven and bake at 175 degrees for 30-35 minutes.

Allow the finished bread to cool completely, then slice and serve with your favorite dishes.
