Heat a non-stick skillet to medium low heat. Lightly spray with oil. Slice an avocado with the skin ON lengthwise, forming one thick slice in the middle. (You will have some leftover avocado pieces).

Remove the seed and use a small cookie cutter to make a hole in the center of your thick slice.

Place the avocado slice in the pan. Crack a medium sized egg into the center of the hole. Cover and cook for a minute or two, until the egg is as you like it.

Season with salt and pepper and serve.
