Bake the eggplant until tender, for about 20 minutes per side.
Remove the eggplants from the oven, but keep the oven on. Top each eggplant with marinara sauce, mozzarella, and Parmesan.

Notes
Seasonings, especially salt, are guidelines. Adjust to taste.
I don't peel the eggplant. Some people worry that the eggplant skin will give this dish a bitter taste, but I don't detect any bitter aftertaste, and the dish looks so much prettier with the dark-colored eggplant skin. However, if you worry about it, there's no harm in peeling the eggplant.
You can use crushed pork rinds instead of almond meal.
You can keep the leftovers in a sealed container in the fridge for up to 4 days. They actually taste good cold! But you can also reheat them uncovered in a 350°F oven.
