Add a side salad to this frittata for a fantastic and easy weeknight meal.
Preheat oven to 400° F.
Heat the olive oil in an oven proof sauté pan and cook leeks and spinach for 4 to 5 minutes. Stir in the red pepper.
In a separate bowl, whisk the eggs, salt, pepper and thyme, and pour into the pan with the vegetables. Top evenly with goat cheese and let cook for another 2 minutes, until the eggs begin to set.
Place the pan into the preheated oven and bake for 7 to 8 minutes until fully set and cheese is melted.
