Start by peeling and slicing the plantains. You want to slice them lengthwise so that they are long and thin.

Heat a frying pan over medium-high heat and add a little bit of oil. Once the oil is hot, add the plantains and fry them until they are golden brown on both sides. Remove them from the pan and let them cool.

While the plantains are cooling, you can start on the filling. Brown the ground beef or chicken in a pan over medium heat. Once it's cooked through, remove it from the pan and set it aside.

In the same pan, add the diced onion and green bell pepper. Saute them until they are soft and translucent, then add the minced garlic and cook for another minute or so.

Add the cooked ground beef or chicken back to the pan, along with the dried oregano and ground cumin. Season with salt and pepper to taste. Mix everything together and cook for another few minutes until the flavors have melded together.

Take a slice of the fried plantain and flatten it out with a rolling pin or the back of a spoon. Place a spoonful of the filling in the center of the plantain slice, then roll it up tightly.

Heat up some more oil in a frying pan over medium-high heat. Once the oil is hot, add the rolled-up Piononos to the pan and fry them until they are crispy and golden brown on all sides.

Remove the Piononos from the pan and place them on a plate lined with paper towels to absorb any excess oil.
