Ingredients for Pork Tenderloin Sandwich Recipe
Pork tenderloin: A lean and tender cut of pork, perfect for quick cooking and frying.
Flour: Used to coat the pork, helping the egg and breadcrumbs adhere.
Eggs: Beaten to create a sticky surface for the breadcrumbs to cling to.
Breadcrumbs: Provide a crispy coating for the pork when fried.
Salt: Enhances the flavor of the pork.
Black pepper: Adds a touch of heat and depth to the seasoning.
Sandwich buns: Toasted to add a bit of crunch and warmth to the sandwich.

Technique Tip for This Recipe
When pounding the pork pieces to the desired thickness, place them between two sheets of plastic wrap or parchment paper. This not only helps to prevent the meat from tearing but also keeps your work area clean. Use a meat mallet or a rolling pin to evenly flatten the pork. This ensures that the pork cooks uniformly and remains tender.

How to Store or Freeze This Sandwich
- Allow the cooked pork tenderloin to cool completely before storing. This prevents condensation from forming, which can make the breadcrumbs soggy.
- Wrap each piece of pork individually in plastic wrap or aluminum foil to maintain freshness and prevent freezer burn.
- Place the wrapped pork pieces in an airtight container or a resealable freezer bag. Label with the date to keep track of storage time.
- Store the pork in the refrigerator for up to 3 days. If freezing, it can be stored for up to 2 months.
- To reheat, thaw the pork in the refrigerator overnight if frozen. Preheat the oven to 350°F (175°C). Place the pork on a baking sheet and cover with foil. Heat for about 15-20 minutes or until warmed through.
- For the sandwich buns, store them in a bread box or a resealable bag at room temperature for up to 2 days. For longer storage, freeze them in a resealable bag for up to 1 month.
- Keep the mayonnaise in the refrigerator and use within its expiration date. Do not freeze mayonnaise as it can separate and become unappetizing.
- Store shredded lettuce and sliced tomato in separate airtight containers in the refrigerator. Use within 2-3 days for optimal freshness.
- When ready to assemble the sandwiches, re-toast the buns if desired, and layer with the reheated pork, fresh lettuce, and tomato. Spread mayonnaise on the buns just before serving to maintain the best texture and flavor.
How to Reheat Leftovers
Preheat your oven to 350°F. Wrap the pork tenderloin sandwiches in aluminum foil to keep them moist. Place them on a baking sheet and heat for about 15-20 minutes until warmed through.
If you prefer a quicker method, use a microwave. Place the sandwich on a microwave-safe plate and cover it with a damp paper towel. Heat on medium power for 1-2 minutes, checking halfway to ensure it heats evenly.
For a crispy exterior, reheat the pork tenderloin in an air fryer. Set the air fryer to 350°F and heat the sandwich for 5-7 minutes. This will help maintain the crunchiness of the breadcrumbs.
If you have a toaster oven, it can also be a great option. Set it to 350°F and place the sandwich on the rack. Heat for about 10-15 minutes until the pork is warmed through and the bun is toasty.
For stovetop reheating, use a skillet over medium heat. Add a small amount of oil and place the pork tenderloin pieces in the skillet. Cover with a lid and heat for about 3-4 minutes on each side until warmed through. Toast the buns separately in the same skillet for a minute or two.
