Creating the Prosciutto Egg Panini is straightforward and delightful. Follow these steps:

1. Heat the Pan: Preheat a skillet or panini press over medium heat.
2. Prepare the Bread: Lightly brush one side of each slice of bread with olive oil or butter.
3. Cook the Eggs: Crack the eggs into the skillet, season with salt and pepper, and cook until the whites are set but the yolks are still runny, about 3-4 minutes.
4. Assemble the Panini: On the unbuttered side of one slice of bread, layer the prosciutto, cooked eggs, cheese, and any greens if using. Top with the second slice of bread, both sides facing out.
5. Grill the Panini: Place the sandwich in the skillet or panini press. Cook on medium heat until the bread is golden brown and the cheese is melted, approximately 3-4 minutes per side in a skillet or 5-7 minutes in a panini press.
6. Slice and Serve: Once cooked, remove from heat and let it cool slightly. Slice in half and serve immediately.

These simple steps will ensure the perfect Prosciutto Egg Panini that is bursting with flavor and texture.
