Ingredients

  • 2 cups egg whites about 12 eggs
  • 3 Tbsp full fat dairy like milk, sour cream, cream cheese, or heavy cream
  • ½ cup crumbled feta cheese 50 g
  • ½ cup grated parmesan cheese 50 g
  • 1 Tbsp olive oil 15 mL
  • 2 cups sliced mushrooms 170 g

  • Saute: Heat oil in a large, oven-safe skillet over medium heat. Add mushrooms, cooking until they have released their moisture and become soft, about 5 minutes. Roughly tear up the spinach and add it to the pan. Stir and cook until it wilts down, about 1 minute. Stir in the salt.

  • Bake: Sprinkle remaining cheese on top of the frittata. Transfer the pan to your preheated oven and cook for 8 to 10 minutes, or until frittata is set. Do not overcook! Slice into 8 pieces. Serve warm or room temperature.
