As much as I wanted to take the 1 hour and 45 minute trip by public transportation to Hackensack NJ to try a White Manna slider, I opted to make them at home.

I used seasoned ground chuck, squashed into a thin patty on a hot cast iron skillet.  Immediately cover the patty with thinly sliced onions and cook until you have a nice gristly char.  Flip, add a slice of cheese, smother with onions, place a sliced potato dinner roll right on top of the burger, and cover the skillet until cooked through.
