Ingredients

Scale
  • 1 tbsp olive oil
  • 2 green onions, white and light green parts sliced
  • 1 cup cherry tomatoes, halved
  • 5 cups baby spinach
  • Kosher salt
  • Pepper
  • 1 1/2 cup liquid egg whites from a carton
  • 1/2 cup full fat or 2% plain Greek yogurt
  • 1/2 cup feta cheese, crumbled

Instructions

  1. Preheat oven to 350 degrees F. Spray a 10.5″ x 7.5″ ceramic baking dish with oil and set aside.
  2. Heat olive oil in a saute pan or frying pan over medium heat. Add green onions and tomatoes. Cook for 3-5 minutes until tomatoes are softened and release most of their liquid, stirring occasionally.
  3. Add baby spinach and a generous shake of kosher salt and pepper. Continue to cook, stirring, until spinach is wilted. Remove from heat.
  4. Whisk together egg whites with the Greek yogurt until well combined, with no lumps of yogurt remaining.
  5. Add the cooked veggies and feta cheese to the egg white mixture. Stir it together gently and add a pinch of salt and pepper.
  6. Pour the egg white mixture into the prepared baking dish.
  7. Bake in the oven for 33-37 minutes. Frittata is done when edges begin to peel away from the sides of the dish, egg whites are no longer translucent, and the center is just a little bit jiggly.
