In a small bowl, combine yogurt, herbs, and salt; set aside. In a medium bowl, combine carrots, cucumber, red onion, and cooked peas.
Lay 1 sheet lavash on a work surface with a long edge parallel to the table. Spoon about 1/4 of yogurt mixture lengthwise down the center of lavash. Lay 1/4 of tomatoes over yogurt, then arrange about 1/4 of carrot mixture over tomatoes. Fold 1 side of lavash over vegetables and roll up to meet other side. Secure with a few toothpicks, then cut in half. Repeat with remaining lavash and fillings.
