Cuban Pork Sandwiches

Preheat oven to 425 degrees. Line a rimmed baking pan with foil; set aside. Pat pork dry with paper towels. Combine onions, olive oil, garlic, lime and orange zests, salt, pepper, and oregano in a medium bowl. Rub mixture on pork.

Heat a large skillet over medium heat. Sear pork on all sides, about 10 minutes. Place on prepared baking pan. Bake for 25 minutes or until done (145 degrees). Transfer pork to a cutting board; let rest for 10 minutes. Cut into thin slices.

Spread 1/2 teaspoon mustard on each bread slice. Top half of the bread slices with pickle slices, pork tenderloin slices, ham, turkey, and Swiss cheese slices. Top with remaining bread slices.

Spray a grill pan with nonstick spray; heat over medium-high heat. Grill sandwiches in batches for 6 minutes or until bread is golden brown and cheese is melted, turning once halfway through.
