1-First step: Season and marinate the pork Start by patting the pork tenderloin dry with paper towels. This helps the seasonings stick and lets the meat brown better later. In a bowl, combine the orange juice and zest, lime juice, minced garlic, cumin, oregano, smoked paprika, crushed red pepper flakes, kosher salt, and black pepper. Place the pork in the mixture and turn it until every side is coated. If you have time, let it sit for 20 to 30 minutes so the flavor can sink in.

2-Second step: Cook the pork Heat a skillet over medium-high heat with a little oil. When the pan is hot, add the pork tenderloin and sear it on all sides until it has a nice golden color. Then lower the heat to medium and keep cooking until the center reaches 145°F. For most tenderloins, this takes about 15 to 20 minutes total, depending on thickness. Use a meat thermometer if you can, since that is the easiest way to keep the pork juicy. Once the pork is done, transfer it to a cutting board and let it rest for 5 to 10 minutes. Resting matters because it helps the juices stay in the meat instead of running out when you slice it.

3-Third step: Slice the pork and prep the sandwich fillings After the pork rests, slice it thinly against the grain. This makes each bite more tender and easy to chew. While the pork cools slightly, slice the ciabatta rolls and set out the ham, Swiss cheese, pickles, and Dijon mustard. Keeping everything ready makes sandwich assembly fast and smooth.

4-Fourth step: Build the sandwiches Spread Dijon mustard on the cut sides of each ciabatta roll. Add a layer of sliced pork, followed by ham, Swiss cheese, and pickles. Try to keep the layers even so the sandwich presses neatly and each bite has a good mix of flavors. Close the sandwiches gently so the fillings stay in place. If you want a stronger mustard flavor, add a little extra Dijon on one side. If you like more tang, use dill pickles. Bread and butter pickles will give a sweeter finish.

5-Fifth step: Press and toast Heat a skillet or sandwich press over medium heat. If you are using a skillet, place the sandwiches in the pan and press them down with another heavy skillet or a foil-wrapped brick. Cook for about 3 to 4 minutes per side, or until the bread is crisp and golden and the cheese has melted. If the bread browns too quickly, lower the heat a bit so the inside has time to warm through. You want the outside crunchy, but not burned, and the inside warm, gooey, and packed with flavor. That balance is what makes Cuban Sandwiches so satisfying.

6-Final step: Slice and serve Remove the sandwiches from the heat and let them sit for a minute before slicing. Cut each one in half on a slight diagonal for a classic look. Serve them hot while the cheese is still soft and the bread is crisp. These are wonderful on their own, but they also pair nicely with plantain chips, a simple salad, or black beans.
