Notes

Find the perfect bread: I love serving my pot roast sandwiches on hard, crusty bread.
Try out a different cheese: Mix up the flavors and try out a different cheese like pepper jack cheese, or mozzarella cheese.
Add more vegetables: Like mushrooms, or add some peppers onto your sandwich!
Don't forget about the au jus: Add a few spoonfuls of leftover au jus on top of your sandwich to add extra moisture to the sandwich.

Skillet instructions:

You can also use a pain to cook these pot roast sandwiches: heat a skillet over medium-low heat and cook for 5 minutes on one side. Flip and cook for an additional 5-6 minutes, or until golden brown.
