This recipe is a leftover makeover starring last week’s slow cooker roast beef. It is also from Donya at A Southern Soul and it is a winner! I fixed these for lunch on a cold snowy day a few weeks ago and they hit the spot. These will definitely be made again and again.
3-4 cups leftover slow cooker roast
1/2 cup beef stock
1/2 onion diced
salt & pepper to taste
4-6 hoagie rolls
4 tbsp. butter, divided
sliced provolone cheese
In a medium saucepan, add the roast beef and beef stock. Bring to a low simmer and continue to cook for approximately 10 minutes or until most of the liquid has reduced.
Melt 1 tbsp. butter in a skillet and add the diced onion. Season with salt and pepper then cook the onions until they are golden and soft.
Preheat the oven to 375 degrees. Spread a little butter on the inside of each hoagie roll then layer some of the beef, cooked onion and a slice of provolone cheese. Wrap each sandwich in aluminum foil. Bake for 5 to 8 minutes or until the cheese is melted. Serve and enjoy!
