Brown your choice of meat in a skillet.
Add sazón, onion, lime juice, and tomato paste.
Let it simmer until the flavors come together.
Peel the ripe plantains and boil them in salted water until tender.
Once cooked, mash them with butter and a little of the boiling water until smooth and creamy.
For more depth, mix in a bit of the meat gravy into the mashed plantains. This is a little secret that makes the pastelón extra delicious.
In a greased baking dish, spread a layer of mashed plantain, then a layer of meat, followed by another layer of plantain.
Generously sprinkle shredded mozzarella on top.
Cover with foil and bake at 350°F (175°C) for 45 minutes. Uncover and bake for another 15 minutes, or until golden and bubbly.
