Toffee (made out of Saltines)

This is very easy and tastes like English Toffee

1 sleeve (about 37) Saltines
1 cup butter
1 cup brown sugar
1 to 1-1/2 cups chocolate chips
¾ cup chopped nuts or almonds (optional)

Foil and lightly grease a sheet pan. Line the pan evenly with saltines. Boil 1 cup butter and 1 cup brown sugar for 5 minutes stirring frequently while boiling. Pour evenly over saltines and bake in 350 degree oven for 5 minutes. Immediately remove from oven, put chocolate chips on top and frost after melted. Sprinkle with chopped nuts if desired. Refrigerate and break into pieces when hard. Tastes best when served cold.
