What a better use of yesterday’s leftover roast beef and gravy than a hot roast beef sandwich? Growing up, I ate a lot of these. They were a quick and easy supper before the days of microwaves. Most every local café, served hot roast beef sandwiches with a big dollop of mashed potatoes. I haven’t seen a hot roast beef sandwich on a menu in years. If they’re out there, I guess I haven’t been going to the right restaurants.
The ingredients are pretty straightforward – leftover roast beef, leftover gravy and bread. I prefer reheating gravy and meat the old school way on top of the stove vs. using the microwave.
Reheat gravy in saucepan. Add water as necessary and stir occasionally while reheating over medium heat. Put a small amount of beef broth or water in a small frying pan. Add roast beef. Cover and let warm up over medium heat.
In a few minutes when everything is heated through, pile roast beef on a slice of bread. Put another slice on top and smother with gravy.
