Preheat the oven to 350F and cover a small pan with foil.
Melt the butter over medium heat then stir in the honey. It should get bubbly and foamy pretty quickly.
Add the nuts and cook, stirring, another minute.
Sprinkle the sugar over the nuts and cook another minute, stirring.
Put the nuts on the baking pan and bake about 4 minutes.
Let them cool. (I just lift the foil off the pan and onto a rack.)
Break apart and add to salad. Store leftovers in the refrigerator for a week or freeze for longer keeping.
