Preheat your oven to 400°F (200°C) and line a large sheet pan with parchment paper for easy cleanup.
Dice the chicken breast into 1-inch cubes and chop the broccoli and red bell pepper into bite-sized pieces.
In a large mixing bowl, combine the chicken, broccoli, and peppers with the olive oil, turmeric, garlic powder, sea salt, and black pepper.
Toss everything thoroughly until the chicken and vegetables are evenly coated in the golden spice mixture.
Spread the mixture across the prepared sheet pan in a single layer, ensuring enough space for the ingredients to roast rather than steam.
Roast in the oven for 15 minutes, then remove the pan and add the cooked jasmine rice, tossing it with the juices on the pan.
Return to the oven for another 3-5 minutes until the chicken is cooked through and the rice is heated and slightly crispy.
Garnish with freshly chopped parsley and serve immediately while hot.
