In a small bowl combine barbecue sauce and ranch dressing.
Place tortillas on a clean surface and spread a spoonful of dressing over tortilla. Divide the quinoa and bacon between the tortillas. Top with cheese, tomatoes, red pepper, olives, lettuce and avocado. Drizzle with additional dressing. Roll tortilla up tightly and secure with toothpicks.
Meanwhile, make the dressing by whisking together ingredients in a small bowl. Stir in refrigerator until using.
Note: If you want a thinner dressing, reduce yogurt to ⅓ cup.
