Toast bread and bacon slices on the grill. Toss Pit Beef and sliced ham on grill to warm before placing on sandwich. Shred lettuce. Assemble the sandwich in this order:1 slice bread, lettuce, BBQ sauce, ham, another slice of bread, bacon, mayo, tomato, Pit Beef, mac and cheese and final slice of bread.
Pit Beef:
Preheat a charcoal grill to 400 degrees F.
Sprinkle beef with rub and grill over direct heat, turning occasionally, until a nice crust forms, about 1 hour 30 minutes. Don't overcook. Rare with a nice char is best because we are going to throw the sliced meat back on the charcoals to heat up before putting on sandwich. Cool completely, then slice about 1/2-inch thick.
