White Castle Slider Knock Offs

I tried another recipe recently, with chopped up onion and bouillon instead of the lipton soup mix.  I didn't like them nearly as well - the recipe below is our favorite so far.


1 1/2 lbs ground chuck
1 (4 tablespoon) envelope onion soup mix
1 egg
1/2 teaspoon pepper
2 tablespoons water
1/3 cup breadcrumbs

24 small square dinner rolls (Hawaiin Rolls are great!)

Cheese (optional.  American is traditional, but I will not use "American" cheese, we usually use Muenster.  Sometimes provolone.)
pickle (optional)

1/2 cup mustard
1/2 cup ketchup

Preheat oven to 400°F. Mix first 6 ingredients and press into an ungreased 10 by 15 inch  pan. (I use my Pampered Chef bar pan) Prick with a fork. Bake for 10 minutes.

Drain off juices (if there's a lot of excess).

Cut into 24 squares. Place squares on dinner rolls.  (I use hawaiin rolls, because I can get them at Sam's club, and that is about the only place I shop. 

Combine mustard and ketchup and spread on rolls. Top with pickles and cheese, if desired.

Makes 24 sliders.
