Add the oil or butter to a nonstick skillet over medium heat, and add slices of meatloaf. Heat until golden brown and warmed through, about 2-3 minutes per side.
1 slice Meatloaf, 1 Tablespoon Olive oil
Once nicely toasted, top the meatloaf with cheese, and continue heating until melted. A lid can help make this process faster!
½ cup Shredded cheese
Set the toasted meatloaf aside, and add the sliced buns to the skillet, cut-side down. Heat until nicely toasted, about 3 more minutes.
1 Hoagie roll
Once toasted, remove the buns from the skillet and spread tomato sauce on both sides. You can also use ketchup or meatloaf sauce.
½ cup Tomato sauce
Top the bread with tomato slices, lettuce, and meatloaf, then close the sandwich.
1 slice Lettuce, 1 slice Tomato
Pierce the sandwich with a toothpick if desired, then serve and enjoy!
Notes
Make a toasted, pressed sandwich by placing the fully assembled sandwich back in the skillet and weighing it down with another skillet on top! I recommend doing this before adding lettuce so it doesn't wilt.
Take your pick on the sauce you add! When I use Italian meatloaf, I like to use tomato sauce. But when I've made a classic meatloaf, I prefer meatloaf sauce, BBQ sauce, or ketchup!
If you plan to make these sandwiches ahead of time, protect the bread from getting soggy by placing lettuce on both sides of the bread and spreading the sauce on the lettuce instead of the bread itself.
You can use any kind of cheese; Swiss, Monterey Jack, Pepper Jack, and Mozzarella are my favorites, but so long as it's a good melty cheese, the type is up to you! (My grandkids like cheddar cheese the most, go figure!)
