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, then toss them with 0.25 tbsp of olive oil and a pinch of the salt and pepper on the prepared tray.
Roast the vegetables for 18-20 minutes until they are tender and slightly caramelized at the edges.
While vegetables roast, season the chicken breast with dried oregano and the remaining salt and pepper.
Heat 0.25 tbsp of olive oil in a skillet over medium-high heat and sear the chicken for 5-7 minutes per side until golden and cooked through.
In a small saucepan, heat the remaining 0.25 tbsp of olive oil and sauté the minced garlic for 30 seconds.
Add the dry basmati rice to the saucepan and toast for 1 minute before pouring in the chicken broth.
Bring the broth to a boil, then reduce heat to low, cover, and simmer for 15 minutes or until the liquid is absorbed.
Remove rice from heat, let it sit covered for 5 minutes, then fluff with a fork and stir in the lemon zest and chopped fresh parsley.
Slice the chicken and serve it alongside the lemon herb rice and roasted vegetables.
