Bring the chicken broth and 2 cups of water to a boil.
While you a waiting for the broth and water to boil, heat your oven to 400 degrees, place the bacon on a foil covered baking sheet, and put it in the oven to bake. It will be crisp after 8-10 minutes.
Once the broth and water boil, add the chicken, and let it cook in the boiling water for 5-6 minutes, until the center is no longer pink. Then remove from the water and let sit to cool.
Drain and rinse the black beans. Chop the tomato and avocado, and either dice or shred the cheese.
Use two forks to shred the chicken.
Remove the bacon from the oven, blot it with a paper towel and crumble it.
You can either divide the brussels sprouts between two bowls and arrange the ingredients on top like I did, or you can toss everything together in a bowl.
