I may or may not make Mississippi Pot Roast just for these sandwiches.

Although delicious on mashed potatoes, in a toasted sub roll with provolone cheese is my favorite way to enjoy it. For this sandwich I whip up a simple roasted garlic aioli and crispy fried onions and sandwich that with shredded pot roast and provolone cheese.
