  1. Heat oven to 425F / 218C.

  2. While oven is heating, heat a 10.5” to 12” (26 cm to 30 cm) oven-safe skillet over medium-high heat. (Note: skillet size is for 4 servings. If customizing, use a larger or smaller skillet, or you can transfer the cooked filling to a muffin tin and top it with the egg mixture before baking.)

  3. To heated skillet add cooking oil and then onions to heated oil. Saute until tender, 3 to 5 minutes.

  4. Add mushrooms and saute until very tender and golden brown, 6 to 8 minutes. Season with some salt.

  5. Stir in spinach leaves until slightly wilted, 3 to 4 minutes more.

  6. Pour egg mixture over vegetables and stir to combine.

  7. Crumble feta over top.
