Instructions

1. Heat a large skillet over medium heat. Add ground beef and onion soup.
2. Stir and cook until beef is cooked through. Drain and discard any excess grease.
3. Remove from heat. Stir the mayonnaise and shredded cheese. Set aside. At this point, you can store the meat mixture in the refrigerator overnight and proceed with the below steps the day of your party.
4. Line a cookie sheet with foil. Split buns and put the bottom of the buns on the sheet.
5. Put a slice of cheese on the bottom of the bun. (This keeps the bun from getting soggy from the meat before baking.)
