Cook bacon in a skillet over medium heat for 8 to 10 minutes until crisp. Drain and let cool for 2 minutes.
Mix mayonnaise, yogurt, lemon juice, chives, dill, garlic powder and salt until smooth.
Spread ranch mixture over the cut faces of both sub rolls. Put half the dry lettuce on each bottom roll.
Fold smoked turkey over the lettuce, add dry roasted-pepper strips and 2 bacon slices per sandwich, breaking the bacon only as needed to fit.
Close the rolls, cut across the middle and serve promptly while the bacon remains crisp.
