Preparation:
Preheat oven to 450 degrees.
Remove the pit, and score/poke the avocado halves.
Pour some olive oil into a ramekin or small bowl, add salt and pepper to taste, stir well.
{I also added about half a teaspoon of some minced garlic, when I tried this a second time.}
Drizzle the olive oil 'sauce' onto the halves, make sure to get into those nooks! Make them flavorful!
Add as much shredded mozzarella cheese as your avocado can handle, sprinkle some shredded/grated parmesan on the top.
Place halves {cheese side up!} on a baking sheet and pop into the oven. Bake for 10-15 minutes, or until cheese is a bubbly, beautiful, golden brown.
