These were a Midwest staple when I was growing up there.
The freshly cooked mixture is simple and delicious.
2 tablespoons dried chopped onions
3 tablespoons water
1 lb lean ground beef
1 1⁄2 cups chicken broth
1⁄2 teaspoon salt, less if broth is salted
1⁄2 teaspoon ground black pepper
6 hamburger buns
yellow mustard, to taste
chopped fresh onion
Soak the dried onions in the water.
Break the ground beef into pieces and put into a hot skillet, cooking over medium high heat.
When the onions have begun to soften, add them and any remaining water to the beef as it is browning.
Stir frequently as the meat browns, using a wooden spoon to break the meat into small pieces.
When the meat has browned, add the chicken broth, salt and pepper.
Cook until liquid is nearly gone, this should take 8-10 minutes.
Serve meat on buns with mustard and fresh chopped onions.
Note, I prefer to steam the buns.
