Preheat the oven to 400 °F and prepare a baking dish.
Cut the avocados in half and remove their pits. With a spoon, remove about 1.5 to 2 tablespoons of avocado flesh from the center to create a well big enough to fit an egg. It should be about 3 tablespoons in size.
Place the avocado halves cut side up onto the baking dish, then crack an egg into the center of each avocado. Be careful not to break the yolk.
Season with salt and pepper and bake for 7 minutes.
Remove from the oven and sprinkle with grated cheese on top (and optional bacon pieces). Bake for another 5-10 minutes or until the egg is how you like it. See Notes & Tips for reference.
Serve with minced parsley and diced bell pepper sprinkled on top.
