In a small bowl, combine the ranch dressing, sour cream, 1 teaspoon of taco seasoning, and salsa. Stir until well blended.
Cover the bowl with aluminum foil and refrigerate until ready to serve.
Season the Chicken:
To a microwave-safe bowl, add the shredded rotisserie chicken, 1 tbsp taco seasoning, and prepared beans.
Cover the bowl with plastic wrap and microwave for 2-3 minutes to heat through.
Warm the Tortillas:
Heat tortillas in a dry skillet over medium heat for about 30–60 seconds per side until warm and pliable. (This isn't 100% necessary, but I love using warm tortillas.)
Assemble the Tacos:
Spoon the seasoned chicken and bean mixture onto each tortilla.
Top the chicken mixture with lettuce, tomato, green onions, cheese, and a dollop of the creamy salsa ranch.
Serve:
Serve immediately with extra dressing on the side if desired.
