Steps
1. Heat a non-stick skillet over medium heat and add the butter, allowing it to melt.
2. Toast the slice of bread in the skillet until golden brown on both sides, about 2-3 minutes per side.
3. In the same skillet, crack the egg, season with salt and pepper, and cook to your desired doneness (sunny-side up or over-easy).
4. Once the egg is cooked, sprinkle the shredded mozzarella cheese on top and cover the skillet for 1 minute, allowing the cheese to melt.
5. Place the toasted bread on a plate, top with the cheesy egg, and garnish with fresh basil leaves if desired.
6. Serve immediately and enjoy your healthy Italian delight!
