Heat an indoor or outdoor grill over medium-high heat.
Prepare hash browns normally according to package instructions.
In a large bowl, combine beef and soup mix until thoroughly incorporated; shape into 4 patties. Place on grill, and cook 3 minutes per side, or until cooked to desired preference. Place a slice of cheese on each burger in the last 2 minutes of grilling. Transfer burgers to a plate to rest. Grill the rolls for 1-2 minutes, or until toasted.
Place burgers on bottom halves of rolls; top with hash browns and roll tops.
