1. Prepare the ingredients
2. Separate the egg whites and put them into an oil-free and water-free bowl, and put the two egg yolks into two small bowls.
3. Put the whole wheat toast in a baking dish lined with aluminum foil, preheat the oven at 150 degrees for 5 minutes, put the toast in the preheated oven and bake for 2 minutes (this step can be omitted if you don’t like crispy toast)
4. Put a pinch of salt in the egg white and beat with an electric whisk to a small sharp corner of hard foam
5. Egg bubbles piled on toast slices
6. Leave a space in the middle, pour in egg yolks, sprinkle a little black pepper
7. Put it in the preheated oven and bake at 150 degrees for 20 minutes
8. Pay attention to the coloring of the egg white bubble and adjust the time (this is what it looks like when it is baked for 15 minutes)
9. The egg whites are baked into golden and ready to be out
