Greek Salad Nachos

This vegetarian nacho recipe is a fun combination of two favorites--nachos and Greek salad. It uses whole-grain pita chips instead of the tortilla chips used in traditional nacho recipes, and it's loaded with the classic fresh vegetables in Greek salad as well as creamy hummus and salty feta cheese. And it doesn't even need the oven! Easily doubled, this makes a great appetizer or light dinner.
