Preheat oven at 400ºF. Cut avocados length-wise in half and remove pit. Depending on the size of the pit and your eggs you may want to widen the hole. The deeper the hole the longer the baking time.
Place the cut avocado in a small baking dish, open side up. Crack one egg into each half and season with salt and pepper.
Baking time depends on the depth of the hole and how you like your eggs. Baking time can take up to 40 minutes if you like your eggs well done.
Top your eggs with tomatoes. You can add chives or parsley
