Preheat your oven to 350 degrees F.
Peel the plantains like you would a banana, then slice each one into 5-6 pieces.
Brush with Mazola corn oil, then air fry at 350 degrees for 15 minutes, or until they're caramelized and cooked through. Flatten the cooked plantains with the underside of a plate.
Grease a 9" x 9" baking dish with corn oil and cover the bottom of the pan with slices of the cooked sweet plantain. Add half of the picadillo, and 1/4 of the mozzarella cheese.
Repeat with another layer of plantains, meat, and cheese (reserve the remaining 1/2 cup of cheese). Top with a final layer of plantains.
Top with the remaining cheese, then pour the beaten eggs all over the top. Tip the pan back and forth to distribute the eggs.
Bake the pastelon at 350 degrees F for 20-30 minutes, until the egg is set and the top of the pastelón is bubbly and golden brown.
