Preheat oven to 400 F/204C
In a mixing bowl combine:
1 cup yogurt
1 1/2 cups olive oil
6 eggs
2 cups finely chopped leeks (depending on your size 2-4)
2 cups crumbled feta
In another bowl combine:
3 cups flour
1 cup corn flour
2 teaspoons baking powder
Combine the dry ingredients into the wet ingredients. Mix well. Place in a 13x9 baking pan and spread evenly.
Bake for 30-40 minutes until a toothpick comes out clean.
For a deeper flavor in the leeks, sauté them with olive oil, salt, and pepper before adding them to the mix.
Enjoy!
