Pour the sugar in your skillet and turn the heat to medium-high.  When the sugar starts to melt stir in the nuts.  Add the cinnamon & salt & continue stirring.  The sugar will begin to clump.  Then it will begin to melt.  Keep stirring everything around as the sugar melts and coats the nuts.  When the nuts are light brown and coated with sugar they are done.

Move the nuts to a sheet of foil or parchment paper in a single layer to cool.  Don’t worry if you have some clumps of nuts.  Once they are cool they can easily be broken apart by hand or by a swat from a wooden spoon.
