What’s in Watergate Salad?

There's a good chance someone's going to bring a dish of Watergate salad over for Christmas. The fluffy green concoction was first created back in the 1970s around the time former President Richard Nixon resigned. It is a mixture of pistachio pudding, whipped cream, pineapple, marshmallows, and chopped nuts. Chef Danielle Sepsy of the Hungry Gnome showed Inside Edition’s Les Trent how to make the delicious treat.
