Instructions

1. Preheat the oven to 375°F (190°C).
2. Heat a medium-sized, oven-safe skillet over medium heat and add the olive oil.
3. Add the diced ham to the skillet and sauté until it turns a light golden brown, about 3-4 minutes.
4. Add the peas to the skillet and stir well, cooking for another 2 minutes until they are heated through.
5. In a separate large bowl, whisk together the eggs, milk, Parmesan cheese, salt, and freshly ground black pepper until well combined.
6. Pour this egg mixture over the ham and peas in the skillet, ensuring all ingredients are evenly covered.
7. Allow the mixture to cook undisturbed for 2-3 minutes, or until the edges start to set.
8. Transfer the skillet to the preheated oven and bake for 12-15 minutes, until the frittata has set and the top is a beautiful golden brown.
9. Remove the skillet from the oven and let the frittata cool for a few minutes before slicing into wedges.
10. Serve the frittata warm, garnished with a little extra grated Parmesan cheese if desired, and enjoy!
