As most muffin recipes, they are easy and quick to be prepared; for this reason they can be served for a week dinner as well, we served these instead of bread together with meat balls.
You can adapt the recipe and for example add grated carrots instead of fried spinach.
If you are using an acid ingredient, as in this case the feta, baking soda will be enough, if not, please use a mixture of baking soda and baking powder.
These muffins can be prepared in advance and reheat for about 3 minutes before serving.
