This meatloaf sandwich with Sriracha mayo combines the classic savory comfort food with the unique spicy bite of Sriracha sauce.
Prepare the Sriracha mayo
In a mixing bowl, whisk together the mayonnaise, Sriracha sauce, lime juice and soy sauce (if using). Store any extra sauce in an airtight container and refrigerate.
Prepare the hoagie rolls
Preheat a skillet or grill pan to medium to high heat. Make a lengthwise cut into each hoagie roll, leaving the two hoagie halves connected on one side. Toast the open hoagie roll cut-side down for 3 to 5 minutes or until the roll is golden brown and the edges of the bread become crisp.
Assemble the meatloaf sandwiches
Spread a generous amount of the Sriracha mayonnaise on the inside of the rolls. Place a slice of meatloaf on each sandwich. Top with tomatoes and lettuce. The meatloaf can be cold or reheated and served warm. Just "shingle" the slices over each other in a baking dish or cake pan with a tablespoon or two of water, cover with foil and cook for 15 to 20 minutes in an oven set to 350 degrees F. Or as a third option, cook the meatloaf in a tablespoon of olive oil in a skillet over medium-high heat to give the meatloaf a crispy texture.
