Simple Toffee - Can be made vegan

I saw Trisha Yearwood make this recipe (it's so good her nephews call it "Crack") and last week it was in my inbox from a recipe site that I belong to.  I finally decided, okay I've got to give this a try.  I've got to say, it's amazing!  I would recommend you definitely try this one.  To make this you will need:

Cooking spray

35 to 40 saltine crackers

2 sticks (1 cup) butter (Vegan - Earth Balance)

1 cup light brown sugar

8 ounces semisweet chocolate chips (Vegan - Carob Chips)

1 cup of chopped pecans or walnuts

1.)  Preheat the oven to 400 degrees.

2.)  Line a cookie sheet pans with parchment paper, spray with nonstick spray and arrange the saltines salt-side down in a single layer.
3.)  In a medium saucepan, melt the butter and brown sugar together and boil until it turns a caramel color, a few minutes. Remove from the heat and pour over the crackers, covering them evenly.
4.)  Put the cookie sheet in the oven for 7 minutes.
5.)  Remove from the oven and pour the chocolate chips over the crackers. Put the sheet back in the oven for a minute or two, to melt the chocokate.  Then spread them over the crackers with a knife.
6.)  Sprinkle with the chopped nuts.
7.)  Put the pan in the refrigerator to cool and firm the chocolate back up. 
8.)  Break into pieces and enjoy!
