Heat the cooked chicken in a large bowl in the microwave until heated through. Then stir in the ranch dressing. Toss the chicken to make sure that it's coated in the ranch dressing.
Warm the tortillas by heating them in the microwave for 30 seconds or frying them for 1-2 minutes.
Then prepare the tacos. Top each of the tortillas with the shredded chicken. Then top with the lettuce, tomatoes, chopped bacon and shredded cheese.
Serve immediately and enjoy!
Notes
This can easily be made with a shredded rotisserie chicken or you can make your own shredded chicken as well.
