Preheat oven to 450 degrees Fahrenheit.

Scrape out the center of each avocado half, enough to hold an egg, then place the halves on a baking sheet.

Sprinkle lime juice over avocado halves, then add a dash of salt to each avocado.

Break an egg - yolk intact - into each avocado half, then place the baking sheet in the oven.

Bake the avocados for 10 to 12 minutes, or until the egg reaches your preferred firmness.

Remove from oven and sprinkle the avocados with black pepper and cayenne pepper powder, then serve.
