1) Cut the pita bread into 1 1/2" wedges.
2) Place the pita on a baking sheet, and bake in a preheated 375°F oven for 12 minutes or so, turning once, till it's dry and crisp. Set it aside to cool.
3) About 10 minutes before you're ready to serve the salad, toss together the vegetables, herbs, olive oil, lemon juice, herbs, and seasonings.
4) Add the bread to the dressed vegetables. Toss to combine (your well-washed bare hands are the best tools here), and serve within 15 minutes or so.
