Scoop enough avocado out to make room for one egg. I just ate that right away. I also made my first hole too small and had a little egg-white overflow. This made me realize that lining the baking pan with foil is a good idea! One large egg is about 1/4 cup, by the way.
Crack the egg into the avocado and place on a baking sheet or pan (that you have lined with foil or greased for easy cleanup if you spill).
Bake for about 20 minutes or until the egg is cooked to the degree of your liking. Check a bit early and watch carefully the last few minutes.
Sprinkle with salt and pepper and herbs of choice.
