I cut it into 8 pieces and it was still overwhelming.

Ingredients:

• 1/4 cup extra virgin olive oil

• 1/4 cup fresh dill, chopped

Procedure:

1. Preheat the oven to 300 degrees. Pour the oil into a large skillet set over medium heat. Add the onion and cook cook for 6 to 8 minutes, stirring occasionally. Dump in the leeks, and cook for another 8 minutes, stirring occasionally, or until very soft. Sprinkle with a pinch of salt, turn off the heat, and set aside to cool.

2. Rub the butter on a 10-inch cake pan.

3. Add the sifted flour and baking powder to a large bowl.

4. Whisk together the eggs and yogurt in another large bowl. Add the feta and dill and fold in. Then whisk in the flour and baking powder. Finally, fold in the cooled onion and leek mixture. Season mixture with salt and pepper.
