Cover a cookie sheet with aluminum foil and spray with cooking spray.
Coat chicken breasts in 1/2 of the spice mixture.
Toss brussel sprouts in 1 tablespoon olive oil (this olive oil is not listed in above ingredients).
Place chicken on one side of cookie sheet and brussel sprouts on the other.
Drizzle 1/2 of the left over spice mixture on brussel sprouts.
Bake for 15 minutes, then turn over chicken and brussel sprouts.
