Dress right before serving, so the pita chips don’t become soggy. And as with any salad, add the dressing slowly and taste as you go.
Make the dressing: In a small bowl, combine the juice from two fresh lemons with 1/3 cup olive oil. Whisk and add salt and pepper to taste.
Heat the oven to 325 F, and place the pita bread on a baking sheet. Bake about 15 minutes until dry and slightly crisp. When cool, break into pieces.
In a large salad bowl, combine all of the ingredients except the pita chips. Slowly add the dressing and the pita chips at the very end. Toss and serve.
