  • 1.5 Tablespoons olive oil or avocado oil
  • 1/2 cup diced onions
  • 8 ounces mushrooms thinly sliced
  • 1 cup chopped kale
  • 2 cloves garlic minced
  • 1/2 teaspoon salt divided
  • black pepper to taste
  • 6 large eggs
  • 1/3 cup milk of choice
  • 1/2 cup grated cheddar cheese optional


  • Preheat oven to 350℉ and grease a 9-inch pie plate with 1/2 tablespoon of oil.
  • Heat remaining tablespoon oil in a large skillet over medium-high heat. Add diced onions and cook for about 3-4 minutes, stirring occasionally.
  • Add sliced mushrooms and cook until tender and browned, about 8-10 minutes. Add garlic and chopped kale. Season with 1/4 teaspoon of salt and a few grinds of black pepper. Cook until kale has wilted down, about 3 minutes, stirring often.
  • Add vegetables to your prepared pie pan and spread into an even layer.
  • While vegetables are cooking, whisk eggs, milk and remaining 1/4 teaspoon of salt, and a few grinds of black pepper in a large bowl. Pour egg mixture over the vegetables in the pie pan and give the pan a little shake to even everything out. Sprinkle the cheese over the top, if using.
  • Bake until set and lightly golden brown on the top, 20 to 25 minutes. Allow to cool for 10 to 15 minutes then slice into wedges. Serve warm.
