Preheat oven to 350 degrees. Spray a 9 inch pie plate with cooking spray or coat with olive oil, set aside.

In a large skillet, add olive oil over medium heat. Add onion and saute until translucent.

Add garlic, mushrooms, kale and carrot. Season with sea salt and pepper if desired.

Add vegetable broth and saute until kale begins to wilt. Remove from heat and set aside.

Blend together eggs and Greek yogurt until frothy. (I used the blender, but you can simply whisk together in a large bowl.)

Add vegetable mixture into coated pie plate. Top with crumbled feta cheese.

Pour egg mixture on top. Sprinkle with shredded cheddar and layer with tomatoes.

Place in oven for 35-40 minutes or until center is set and the top is slightly golden.

Let cool and enjoy :)
