Whisk together marinade ingredients. Add chicken to a resealable container or plastic bag and cover with marinade. Ensure marinade covers all chicken, then marinate overnight (or at least 1 hour).
Pre-heat oven to 400 degrees.
Heat 1 tsp olive oil in an oven-safe skillet over medium-high heat. Add marinated chicken and brown on each side (3-4 minutes per side).
Transfer skillet to oven and bake for 20 minutes. Remove chicken to a plate and add sweet potatoes to the bottom of the skillet. Add chicken back on top of the sweet potatoes and bake for another 20-25 minutes, or until chicken is cooked through.
Serve with steamed broccoli. Top with sliced green onions and sesame seeds, if desired.
The cooking times listed are for split chicken breasts (with skin and bone). You'll need to cut the baking time to about 30-40 minutes total if using thick cut, boneless chicken breasts.
The nutrition facts listed account for removing the skin from the chicken before eating.
