I recently just made this wonderful thing and it was sooo good. Basically cut the avocado in half, take out the seed, and hollow the hole out a little more. Set oven to 400 degrees. Crack the egg into the avocado and bake for about ten minutes. Just be really careful about not spilling the egg out of the avocado, trust me I have had past experience haha. Feel free to add salt and pepper and other herbs and even cheese! Enjoy. Tell me how it works for you.
