Make the sauce: Combine all ingredients and set aside.
In a large skillet, add the bacon in one layer. Turn to medium-high heat, and cook for 5-7 minutes, flip, then keep cooking until the bacon is cooked to your preference. Remove to paper towels to drain, then chop.
In the same skillet (in the bacon grease!), add the chicken (still over medium-high heat), and sprinkle with pepper. Cook for 5-7 minutes on each side until the chicken is browned and cooked through, then remove to a plate to cool.
When the chicken is cool, use your fingers or 2 forks to shred into bite-sized pieces. Cut the avocado in half, remove the pit, and dice it for serving.
Build tacos! Fill each tortilla with lettuce, chicken, bacon, cheese, tomato, and avocado. Drizzle with the chipotle sauce. Inhale. Enjoy!
