Let’s say you’re reheating a thick, layered beast—like a Cubano or a Philly cheesesteak. Use a slightly different method. Wrap the bottom half (meat and cheese) in foil for the first 5 minutes. This traps steam and melts the cheese without drying out the meat.
Then, unwrap it, add the top bread, and bake for another 3 minutes uncovered. The top gets crunchy, the bottom stays moist, and you achieve what I call the "Perfect Crunch-Squish Ratio." That’s a real term. I just invented it.

When the Oven is Too Much (The Toaster Oven Hack)
If you’re making just one sandwich, a full-sized oven is like using a flamethrower to light a candle. Use a toaster oven instead. It preheats in 2 minutes and uses 70% less energy. That’s a fact from the U.S. Department of Energy, not me—though they probably didn’t test it on a turkey club.
Set the toaster oven to 350°F, and watch your sandwich like a hawk. It can go from gold to charcoal in 30 seconds. The toaster oven is a hot-tempered artist; it works fast and demands attention.
