Sweet Potato Hummus with Toasted Pistachios and Feta

Go into any supermarket and the ever expanding selection of hummus will tell you hummus has become the snack of the moment.   Philadelphia just opened a “Hummusiya” restaurant called Dizengoff, named after the famous food street in Tel Aviv.  A restaurant serving nothing but hummus?  You bet!  Hummus is a no-guilt snack food gaining in popularity because it is nutritious,  packed with good fat, fiber, protein and tons of flavor.  This creamy sweet potato hummus offers a seasonal twist on the traditional hummus.  It is easy to make and such a pretty addition to the menu when presented  in a hollowed out squash.  Serve with warm pita points.
