Rinse the spinach well. Sprinkle with salt and massage it into the spinach leaves. Leave for 5-10 minutes. This softens the spinach leaves a little.
In the meantime preheat the oven to 180°C (350°F) fan setting. Take a 12 cup muffin tray and spray with oil spray.
Start preparing the ingredients in a mixer. Add the feta cheese, egg, milk, softened butter and dill.
Then you can return to the spinach leaves and rinse off the salt. Grab bunches of spinach and squeeze or wring it out like you would a wet cloth, to get all the water out. Pat dry with a paper towel and pop the spinach in the mixer with the other ingredients.
Blend it together until it makes a soft paste. Only blend as much as you have to in order to get the right consistency and spoon it out into a large bowl.
Add in your self-raising flour, wholemeal flour and baking powder. Mix with a spoon until combined.
Spoon the mixture into greased muffin cups.
Sprinkle with grated Parmesan cheese and sesame seeds (optional).
Bake on the middle shelf of the oven and bake for 20 minutes or until golden brown on top.
Remove and let them cool down. Enjoy!
