Preheat the oven at 180°C (350°F) and line a 36x28 cm (14.5x11 inches) baking pan with parchment paper or brush it with olive oil, butter, or margarine. Set aside.
In a large bowl add the olive oil, eggs, and yogurt and stir with a metal whisk until combined and fluffy.
Add spices, baking powder, and flours, and whisk until just incorporated.
Add the cheeses, spearmint/mint, and mix well. The mixture will be moist.
Pour the mixture into the baking pan, level it equally with a spatula, and sprinkle with sesame seeds (if applicable).
Bake for 40-50 minutes, until golden brown at the top.
Remove from the oven and let it cool down for 10-15 minutes.
Cut it into pieces and serve warm or cold.
Enjoy 🙂
