Preheat the oven to 400ºF. Spray a large sturdy baking sheet with cooking spray or line with parchment paper or aluminum foil.
Place the chicken on a prepared baking sheet. Season with salt and black pepper to taste.
In a small bowl, combine soy sauce, lemon juice, honey, and olive oil. Whisk to combine. Drizzle 1/3 of the lemon sauce over the chicken.
Place chicken in the oven and bake for 10 minutes. Meanwhile, combine the seasonings in a small bowl and set aside.
After 10 minutes, remove the baking pan from the oven, flip the chicken and place the green beans and cauliflower around the sides of the chicken.
Sprinkle the chicken and vegetables with seasonings and drizzle 1/3 of the lemon sauce over the vegetables and some more on the chicken.
Return the oven back to the pan and bake for another 10-15 minutes, or once the chicken is cooked through and has reached an internal temperature of 165ºF. If the veggies are done but the chicken is not, you can remove the veggies to a bowl and return the chicken back to the oven until finished cooking.
Drizzle the chicken with remaining lemon sauce and turn the oven to broil. Broil for 2-3 minutes (watching carefully) until the chicken is a golden brown color.
Remove the chicken from the oven and let rest for 5 minutes.
Sprinkle with chopped parsley if desired and serve warm. Enjoy!
