Preheat oven to 180ºC. Line a baking sheet with parchment paper. Set aside.
Heat a large skillet over medium and cook the bacon until crisp.
Spoon out the avocado around the area the pit was to make the hole a bit bigger, then put avocado on the baking sheet. Place a slice of bacon in each avocado half. Crack an egg into each, making sure to keep the yolk in the hole.
Bake for 12-15 minutes until eggs cook through. The yolk will jiggle when if you shake the pan, but whites will be set.
Add salt and pepper to taste and top with chopped chives.
