In a large container that you can seal, whisk together all "chicken ingredients" except the chicken.
Add chicken breasts. Let brine in refrigerator for at least 4 hours or overnight for best results.
When you're ready to start cooking, preheat oven to 400 Fahrenheit degrees.
Place chicken in oven and roast for 25 minutes or until internal temperature of 165 degrees Fahrenheit is achieved.
While chicken is in the oven, heat a large pot or Dutch oven on medium high.
Add olive oil, cabbage, fennel, apple, and onion to the pot. Cook, stirring often, until ingredients are wilted.
Slice chicken and serve over cabbage, fennel, and apple mixture.
Garnish with fennel fronds.
