Have your fast food at home with this recipe for an Arby's Beef n' Cheddar. The fries can be found at the grocery in the frozen section and make it a complete meal.
In a small pot, melt the cheddar cheese with the milk over low heat.
In a medium pot, heat the water over low heat and stir in the beef bouillon cube.
Once the cheese is melted and the beef bouillon cube has dissolved, place the roast beef in with the beef flavored water. You only want it to heat up until it's warm. If you overcook it, the roast beef will become tough. I recommend 1-2 minutes at the most.
Quickly add the roast beef and then top with the melted cheese.
Serve immediately. You can serve with the Arby's fries from the frozen section of your grocery store to make a whole Arby's meal.
