Creating a frittata can be straightforward if you follow these easy steps:

1. Preheat the Oven: Begin by preheating your oven to 375°F (190°C).

2. Prepare the Ingredients: Chop your choice of vegetables and cooked meats into small, uniform pieces.

3. Sauté Vegetables: In an oven-safe skillet, heat the olive oil or butter over medium heat. Add the diced vegetables and sauté until they soften, about 5-7 minutes.

4. Whisk the Eggs: In a large bowl, whisk together the eggs, milk, salt, and pepper until well combined and slightly frothy.

5. Add Meat and Cheese: Stir in your cooked meat and half of the shredded cheese into the egg mixture.

6. Combine Mixtures: Pour the egg mixture over the sautéed vegetables in the skillet. Stir gently to distribute the ingredients evenly.

7. Cook on Stovetop: Allow the frittata to cook on the stovetop for about 5-8 minutes, until the edges start to set but the center is still slightly runny.

8. Transfer to Oven: Sprinkle the remaining cheese on top and place the skillet in the preheated oven. Bake for 15-20 minutes or until the center is fully set and the top is golden brown.

9. Cool and Slice: Remove from the oven and let cool for a few minutes. Cut into wedges and serve.

10. Garnish (optional): Top with fresh herbs for an extra burst of flavor.

These steps will guide you in creating a flavorful and satisfying frittata effortlessly!
