Place the dinner rolls in a large lightly buttered skillet, allowing some space between the rolls. Cover with a dish towel or cloth napkin and set aside in a warm place to rise for at least 2 to 3 hours.
When risen, the rolls should be poufy and soft. Brush melted butter onto the rolls. Then sprinkle the rolls with chopped rosemary. Finally, sprinkle with sea salt.
Bake (as instructions on the packet - usually 400 degrees F) for 15 to 20 minutes. Don't be alarmed if you pull them out of the oven and they've risen way over the surface of the pan. Within a minute or two, they'll calm right down.
