Almost White Castle Hamburgers
White Castle sliders are well known in the Chicago area. I believe down South they are called Krystals. This copycat recipe is the closest I have come to the real deal. Serve each slider with American cheese, dill pickle slices, and Düsseldorf mustard.

pounds
plain bread crumbs
⅓
cup

1

1
(1 ounce) package

small
 Preheat the oven to 400 degrees F (200 degrees C).
  Combine ground chuck, bread crumbs, egg, onion soup mix, water, and black pepper in a bowl; press into a 10x15-inch jelly roll pan. Prick holes through the chuck mixture for ventilation while cooking.
  Bake in the preheated oven until browned and cooked through, about 10 minutes. An instant-read thermometer inserted into the center should read at least 160 degrees F (70 degrees C). Drain excess grease.
  Cut chuck mixture into squares the size of the rolls. Place 1 chuck patty in each roll.
