Preheat your oven to 400°F and line a baking sheet with parchment paper.
Dice the zucchini and red bell pepper into bite-sized pieces and toss them on the baking sheet with half of the olive oil, sea salt, and black pepper.
Roast the vegetables for 20 minutes until they are tender and slightly caramelized at the edges.
While vegetables roast, season the chicken breast with sea salt and black pepper, then sear in a skillet over medium-high heat with the remaining olive oil until golden and cooked through.
In a small saucepan, sauté the minced garlic for 30 seconds, then add the jasmine rice and chicken broth, bringing it to a boil before simmering covered for 15 minutes.
Fluff the rice with a fork and stir in the lemon juice, lemon zest, fresh parsley, and the roasted vegetables.
Slice the chicken breast into strips and serve it over the warm, fragrant rice pilaf.
