Method

Frittata

  1. 1

    Prepare the Vegetables

    In a skillet, heat olive oil over medium heat. Add zucchini, butternut squash, and wild mushrooms. Sauté until tender, about 5-7 minutes.

    Mix the Eggs

    In a bowl, whisk together the eggs, tarragon, dill, parsley, salt, and black pepper. Pour the egg mixture over the sautéed vegetables in the skillet.
