Method

• 1.
  Preheat the oven to 200°C. Use an 8cm round cutter to cut a hole in the centre of each bread slice.
• 2.
  Melt butter in a large ovenproof frypan over medium heat. Cook bread, in batches if necessary, on one side for 1-2 minutes until golden, then turn the bread over. Transfer all bread, toasted-side down, back to the pan (or a lined baking tray), then carefully crack an egg into each hole. Season, then bake for 3-4 minutes until eggs are just set.
• 3.
  Transfer to plates, then serve with spinach and hollandaise sauce.
