Now, you can certainly serve this shredded beef on buns the traditional way, like you would pulled pork. But when you get tired of that? These grilled cheese sandwiches are here to save the day.
Place one slice of bread, butter side down, in the skillet.
Top with 1 slice of cheddar cheese, a large spoonful of the shredded beef, another slice of cheddar, a scoop of macaroni and cheese, a third slice of cheddar, and the second piece of bread.
Cook until the bottom piece of bread is crispy and golden. Carefully use a spatula (and your fingers to hold the sandwich together!) to flip. Continue cooking until the bottom slice of bread is cripsy and golden.
