Add the juice from 2 lemons, chicken broth, oregano, basil, garlic powder, salt, and black pepper to a large zip up bag. Place the chicken in the bag, push out the air and zip it up.
Put chicken in the fridge for at least 1/2 hour to marinate.
Cook the bacon, place on a paper towel, and dab up any extra grease.
I used a grill pan to cook my chicken but you could also use a grill. Add the chicken to a preheated grill pan over medium heat. Cook for 3 minutes on each side or until it reaches an internal temperature of 165 degrees F. Assemble the sandwich by placing the lettuce on the hamburger bun, followed by the tomato, chicken breast, cheese, bacon, and BBQ sauce.
