Preheat oven to 400 degrees F. Spread parchment paper over a cookie sheet.
Line cookie sheet with saltine crackers in single layer, leaving some space between each cracker.
In a saucepan combine the sugar and the butter. Bring to a full, rolling boil, then boil for 3 minutes.
Immediately pour over saltines. Do your best to pour some on each cracker, but dont worry about covering each one completely.
Bake at 400 degrees F (205 degrees C) for 7 minutes. Once its been in the oven for 2-3 minutes, it will start to bubble. This is when the candy will cover the crackers on its own. Theyll also move around a bit, so you can see why its important to have a bit of excess parchment paper up around the sides.
Remove from oven and sprinkle chocolate chips over the top. Put back in the oven for 2 minutes.
Spread melted chocolate and top with chopped nuts. Cool completely and break into pieces. Enjoy!
