Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper.
Dice the chicken breast, zucchini, and red bell pepper into bite-sized pieces.
Place the chicken and vegetables on the baking sheet, drizzle with half of the olive oil, and season with half of the sea salt and black pepper.
Roast in the oven for 18-20 minutes, or until the chicken is cooked through and the vegetables are tender and slightly caramelized.
While the chicken roasts, rinse the basmati rice under cold water until the water runs clear.
In a small saucepan, combine the rinsed rice and chicken broth; bring to a boil, then reduce heat to low, cover, and simmer for 12-15 minutes.
Remove the rice from heat and let it sit covered for 5 minutes before fluffing with a fork.
Stir the remaining olive oil, lemon juice, lemon zest, fresh parsley, fresh thyme, and the remaining salt and pepper into the cooked rice.
Divide the lemon herb rice into bowls and top with the roasted chicken and vegetables to serve.
