For the herb muffins with Parmesan, preheat the oven to 200 °C. Grease muffin tin or place paper molds in the wells.
Mix flour and baking powder. Then add baking soda, some herb salt and herbs and mix it all together. In a bowl, mix the flour mixture, eggs, egg whites, buttermilk, olive oil and parmesan until all ingredients are moist. Pour batter into the molds and bake for about 25 minutes.
At the end of the baking time, remove muffins from the oven and let cool briefly in the mold.
Then remove and serve the herb muffins with Parmesan cold or warm.
