Peel and cut open the plantains. Cut in half and into 1/4-inch strips.
Over medium/high heat add the oil and fry the plantains until golden brown on each side (approximately 35 seconds on each side). For less oil, air-fry the plantains approximately 5-7 minutes.
Set aside.
For the meat: In a pan, add the meat, sofrito, onions, and peppers, seasonings and olives if adding. Sauté for a few minutes.
Add the tomato sauce and simmer until the meat is browned and fully cooked.
Preheat the oven to 350°F.
Grease a small square or rectangular baking dish.
Add a layer of the plantains, then a layer of meat, and cheese. Continue to add layers until you run out of plantains (approximately 2-3 layers).
On the final layer of plantains, add the beaten eggs on top of all the layers.
Finish with a top layer of cheese.
Bake the pastelón for 20-30 minutes until the cheese melts.
