Medianoches are usually made with "pan suave," a soft, sweet bread. Since it is not widely available, I've substituted it with 6 inch-long challah rolls, which are sweet and soft like the original.

- For the Pork:
- 1 (3/4 pound) pork tenderloin, trimmed of silver skin and excess fat
- Kosher salt and freshly ground black pepper
- 4 large garlic cloves, minced (about 2 tablespoons)
- 1/4 cup olive oil
- 2 tablespoons juice from 1 orange
- 1 tablespoon juice from 1 to 2 limes
- 1 teaspoon dried oregano

- For the Sandwiches:
- 4 tablespoons unsalted butter, softened

- 4 sweet rolls (see note above), split in half lengthwise
- 8 slices deli ham

For the Pork: Adjust oven rack to upper middle position and preheat oven to 450°F. Line rimmed baking sheet with foil. Poke pork tenderloin all over with knife. Season with salt and pepper. Place pork on prepared baking sheet.
Place garlic and olive oil in small bowl or teacup; oil should completely cover garlic. Microwave 45 seconds. Transfer to medium bowl and whisk in orange juice, lime juice, oregano, and cumin.
Pour garlic mixture over pork tenderloin, rubbing into perforations. Roast until temperature reads 145°F on instant-read thermometer, about 15 minutes. Transfer to cooling rack and cool completely, about 30 minutes. Pork may be prepared one day in advance and refrigerated in an airtight container. Thinly slice pork.
For the Sandwiches: Combine 2 tablespoons butter and mustard in small bowl. Spread the cut sides of the rolls evenly with butter-mustard mixture.
Top roll bottoms with a layer of pork, 2 slices ham, 8 pickle chips, 2 slices cheese, and roll tops. Spread exterior of rolls with remaining 2 tablespoons butter.
Cook sandwiches over medium heat, pressing down with spatula, until crisp and golden, about 4 minutes per side. Alternatively, heat panini press according to manufacturer’s instructions and cook sandwiches until crisp and golden.
Allow sandwiches to set about 2 minutes, then serve.
