Make the filling
Preheat the oven. Add the oil to a pan. Add the garlic and cook. Stir in the spinach. Add the red peppers. Remove it from the heat and set it aside.
Line and fill the tray
Use strips of prosciutto to line the bottom and sides of each muffin cavity completely. Spoon the prepared spinach mixture into each muffin cup.
Crack the eggs
Carefully crack one egg into each muffin cup. Season with black pepper.
Pop the muffin tray into the oven and bake until the eggs are cooked to taste.
Remove the egg cups from the oven. Let them cool for 5-10 minutes before removing them from the tray. Garnish, serve, and enjoy!
