Preheat oven to 350.
Use a greased cookie sheet at work surface so you don't make a huge mess.
Take a small spoon and create a well in the bread. Gently press the spoon all round the edges of the bread until the entire middle is a perfect little bowl for your ingredients. Season your bread with salt and pepper generously, but not excessively.
Next, take a slice of your ham and cut it into quarters. Take two quarters of ham and place them into the little well you created in the bread.
Now, carefully crack an egg on top of the ham. It will spread but it should stay nicely on top of the ham. Season the egg with salt and pepper as well.
Layer shredded cheese along the edges on the bread.
Garnish with very finely chopped spinach.
Put these into the oven for 20 minutes or until the cheese is a golden brown and the eggs are nice and cooked, but still a little gooey.
