Begin by rehydrating the dehydrated onions. In a small bowl, combine the dehydrated onions with 1/2 cup of water and let them sit for about 10 minutes until they are soft and plump.
In a large skillet over medium heat, add the ground beef. Break it up with a spatula and cook until browned and fully cooked through, about 5-7 minutes. Drain any excess fat if necessary.
Once the beef is cooked, add the rehydrated onions, the remaining 1/2 cup of water, and the beef bouillon cube. Stir well to combine. Let this mixture simmer for about 5 minutes until the flavors meld together.
After simmering, sprinkle in the salt and mix well. Taste and adjust seasoning if necessary.
While the beef mixture is simmering, slice your dinner rolls in half. Arrange them on a serving platter or baking sheet with the cut sides facing up.
Spoon a generous amount of the beef mixture onto the bottom half of each roll. Top with a squirt of yellow mustard and a dill pickle slice before placing the top half of the roll on each slider.
