Preheat your oven to 400°F and line a baking sheet with parchment paper for easy cleanup.
Toss the chopped zucchini and red bell pepper with 0.5 tsp of olive oil, a pinch of sea salt, and black pepper, then roast for 20 minutes until tender.
In a small saucepan, combine the dry basmati rice, chicken broth, and minced garlic; bring to a boil, then cover and simmer on low heat for 15 minutes.
Season the chicken breast with dried oregano, sea salt, and black pepper, then sear in a skillet with the remaining 0.5 tsp of olive oil over medium-high heat until golden and cooked through.
Once the rice has absorbed all the liquid, remove from heat, fluff with a fork, and stir in the lemon juice, lemon zest, and fresh parsley.
Slice the chicken into strips and serve it over the lemon herb rice pilaf with the roasted vegetables on the side.
