Prepare the filling: In a bowl, crack the 4 eggs and whisk them. Add in the chopped green onions, grated cheese, salt, and Greek yogurt. Mix well to combine until you get a smooth filling mixture.
Make the batter: In another bowl, whisk together the remaining 3 eggs with the Greek yogurt. Gradually add in the rice flour, salt, and baking powder, stirring until the batter becomes smooth and well-combined.
Cook the dish: Preheat your oven to 180°C (350°F). Grease a baking dish with olive oil. Pour the batter into the dish and evenly spread it out. Gently spoon the egg mixture with green onions and cheese on top of the batter, spreading it out evenly.
Bake: Place the dish in the preheated oven and bake for about 30-35 minutes, or until the top is golden and a toothpick inserted in the center comes out clean.
Serve: Once done, remove from the oven and let it cool for a few minutes. Slice and serve warm as a main dish or side.
