Slice the tenderloin in half lengthwise. In a large bowl or ziploc bag, add the sliced pork, adobo, oregano, salt, lime juice, pepper and garlic. Mix well.
Refrigerate overnight or a minimum of 4 hours.
Cooking the pork tenderloin
In a large skillet heat the oil over medium heat.
Add pork to the skillet. Cook until both sides are browned and pork is cooked through but not dried out.
When pork is done, place on a cutting board and chop into small pieces. Keep skillet with its juices on the side as you will be adding the veggies to it.
In the same skillet you cooked the pork, add onions, olives, peppers, cilantro and pepper.
Cook over medium-low heat until juices are absorbed, pork is beginning to brown more and veggies become tender.
Filling the Empanadas
Place one full tablespoon of the pork filling onto the center of the discs. You may add a piece or two extra if you think they can fit.
With (clean) fingers wet the empanada disc all around. Fold in half and press disc edges down with the tips of a fork until fully sealed. Repeat with all discs. one at a time.
Make sure to place uncooked empanadas side by side and not on top of each other as they will stick together.
Fry the empanadas over medium heat in a large skillet. Make sure not to overcrowd. This is all about cooking the dough and it should take only a couple of minutes on each side.
I like to lay empanadas down on a paper towel lined plate to cool down. About 5 minutes you are good to go! Serve with hot sauce if desired.
