In a bowl, mix together the eggs, milk, honey, and nutmeg until well combined.
Soak the slices of bread in the mixture until well absorbed. The amount of soaking time will vary depending on the type of bread you use and how stale it is. I soaked mine for 10 minutes.
Meanwhile, heat a cast iron pan on medium high heat. Melt 2 tbsp of the butter and once add a few slices of the soaked bread. Make sure not to overcrowd the pan. Cook on both sides until golden brown. Drizzle a bit more on and top before serving.
