In a large mixing bowl whisk together the eggs, olive oil, milk and yogurt until the texture becomes smooth. Slowly add the flour followed by the shredded cheese and green onions.
Preheat the waffle maker to the desired setting.
Apply a little butter to the waffle iron and pour 2 cups of the mixture in the center of the lower grid of the preheated waffle maker and spread evenly, than close the lid. When ready carefully remove the waffle and repeat with the remaining mixture. For best results, serve immediately.
