Slice the avocados and remove the pits. Place avocados inside the foil rings on the baking sheet and brush with olive oil. Scoop out a hole where the pit was. Hole should be large enough to hold one broken egg.
For picture perfect baked avocado eggs: separate egg whites from yolk. Using a spoon, first add the yolk to the avocado hole, then add the egg whites to just cover the yolk.
Slice off a small piece of the bottom of the avocado to make it stand up straight.
Large muffin sized tins can be used in place of baking sheet and foil to keep them straight up and easier to fill.
