White Castle Burgers

1 lb. ground beef or turkey
2 TBS Mayo (light may be used)
1.5 cups shredded cheddar (2% cheese can be used)
1 packet Onion Soup Mix
1 package dinner rolls (like Hawaiian or Sarah Lee)
Brown meat in pan. While browning, cut rolls in half. Leave all tops and bottoms together. Leave tops off, and place bottoms in a baking dish or pan that has aluminum foil in the bottom. Leave enough aluminum foil to cover the tops of the rolls later. When meat is browned, remove fat (if needed), and add in mayo, cheese, and soup mix. I leave the burner on low till all cheese is melted. Place mixture over the top of the roll bottoms. Smear the meat mixture over all the rolls, (you can add in pickles if you like, we do at my house) and place tops on. Wrap in aluminum foil and bake at 375 for 15-20 minutes. This seams the burgers. When done, unwrap and use a knife to cut the sandwiches apart. Let cool and serve.
They are an instant hit... and way more healthy than the real white castles. Bella and my nieces eat these up!
