Reheat as many of the leftovers, from your roast beef dinner, as necessary for the number of people you're feeding. This recipe is enough for 1 serving. Multiply it for each sandwich you want to serve. Trust me when I tell you, NO ONE will know this delicious comfort food meal is made from leftovers. Why tell them?
- 1/4 lb leftover roast beef
- 1/4 cup leftover gravy
- 1/2 cup mashed potatoes (leftover if you have them. If not, I have a fast and easy solution, I'll share.)
- 1 slice french bread, sliced into 1 to 1.5" thick slices
- Heat the mashed potatoes. I think the microwave works best. Use your own leftovers or try pre-made mashed potatoes from the refrigerated case at your favorite market. I use Bob Evans Original brand.
- Reheat leftover roast beef in a skillet on the stove top or in the microwave.
- You'll warm the leftover gravy, as well. Add a small amount of water to thin it, if it has set too thick in the refrigerator. Keep it over medium low heat, in a pan on the stove top, whisking as necessary to bring it back to a smooth consistency.
- Cut a thick slice of French bread. Lightly butter both sides of the bread and toast it. If you're just making one to four hot beef sandwiches, this can most easily be achieved in a skillet on the stove-top. Brown both sides and you're ready to go. (For more than four at a time, you can put them on a sheet tray under the broiler in your oven for a couple minutes.)
- Once all the ingredients are warmed, you're ready to assemble the luscious sandwiches.
- Lay the toasted bread on your plate, top with a layer of the warmed roast beef, then a drizzle of hot gravy.
- Now, add a scoop of mashed potatoes to the top of the stack and drizzle with more gravy.
- Serve hot with your favorite veggie side.
