Instructions

Step 1
Preheat oven to 350 degrees F (175 degrees C

Step 2
Place the bacon in a large, deep skillet, and cook over medium-high heat, turning occasionally, until evenly browned, about 10 minutes. Drain the bacon slices on a paper towel-lined plate.

Step 3
Cut a slit down the center of a loaf of bread, and use a spoon to scoop out the interior, leaving a pocket in the loaf. Line the pocket with 2 slices of processed cheese food. Divide the cooked bacon slices in 4, and stuff each bread loaf with 1/4 of the bacon.

Step 4
Place sliced roast beef and ham onto microwave-safe plates, and top slices with a pat of butter. Cook in microwave oven set on High until the butter has melted, about 30 seconds. Lightly stuff each loaf with 1/4 of the buttered meat slices. Top with sliced American cheese, and stuff a couple of pats of butter into the top of each loaf.

Step 5
Use remaining butter to spread over the outside of each loaf. Generously drizzle dollops of Dijon mustard and mayonnaise over the top of the stuffing.

Step 6
Place loaves on a baking sheet, and bake in the preheated oven until the bread is toasted and the filling is hot and melted, about 30 minutes. Watch carefully to avoid burning bread.

Step 7
Heat the gravy to a simmer over low heat; remove sandwiches from oven, slice into serving portions, and top each serving with a generous helping of hot gravy.
