Place the frozen dinner rolls on a waxed paper lined baking sheet. Cover with plastic wrap. Allow to thaw at room temperature for 30 minutes. The dough should be thawed but still cold.
Butter the bottom and sides of a 12-inch cast iron skillet.
Combine the Parmesan cheese, parsley, and garlic salt into a 1-gallon resealable plastic bag. Shake to combine ingredients well.
Dip the thawed dinner rolls into the melted butter. Toss them in the plastic bag that contains the Parmesan cheese mixture. Arrange side-by-side around the edge of the prepared skillet. Cover with plastic wrap and let rise for 2 to 2 ½ hours, or until doubled in size.
For the Dip
Preheat the oven to 350°F.
In a medium-size mixing bowl, using an electric mixer on medium-high speed, whip together the cream cheese, mayonnaise, sour cream, melted butter, Cajun seasoning, garlic powder, seasoned salt, black pepper, and hot sauce until fully combined.
By hand, mix in 1 cup of the pepper jack cheese, the crab meat, and chives. Unwrap the skillet and pour the cheese mixture into the center of the skillet. Top with the remaining cup of shredded pepper jack cheese.
Bake for 30 minutes, or until the rolls are golden and the dip is heated through, covering the rolls with aluminum foil during the final 10 minutes of baking to prevent over browning, if needed.
Let rest for 5 minutes before serving.
Notes
I used two 6-ounce cans crab meat, well drained. The combined weight of the drained crab meat was a little less than 8 ounces.
