To make the barbecue sauce: Heat all ingredients together in a small pot over medium heat and bring to a bubble. Check seasonings and adjust if necessary. Let bubble, giving it a stir every minute or two, for about five minutes. That's it! Barbecue Chicken Pita Pizza: Preheat the oven to 350 degrees. Place a pita on a baking sheet (no cooking spray is necessary), spread 2 Tbs of BBQ sauce on it. Top with the cooked chicken, then the cheese, then the red onions. Bake for 15 minutes. Pull it out of the oven, sprinkle with the cilantro and talk yourself out of making another one. YUM!!
