Preheat your oven to 375°F (190°C). Grease a muffin tin or line with paper liners.
In a large mixing bowl, whisk together the gluten-free flour, baking powder, and salt.
In another bowl, beat the eggs and then add the milk and olive oil. Mix well.
Pour the wet ingredients into the dry ingredients and stir until just combined.
Fold in the crumbled feta cheese, chopped dill, and parsley.
Spoon the batter into the prepared muffin tin, filling each cup about ¾ full.
Bake for 20-25 minutes, or until a toothpick inserted into the center comes out clean.
Let the muffins cool in the tin for a few minutes before transferring to a wire rack to cool completely.
