Preheat your oven to 400°F and line a large baking sheet with parchment paper for easy cleanup.
Chop the zucchini and red bell pepper into bite-sized pieces and toss them on the baking sheet with 1 teaspoon of olive oil and a pinch of salt and pepper.
Roast the vegetables for 20 minutes, flipping halfway through, until they are tender and slightly caramelized around the edges.
In a small saucepan, toast the basmati rice with 0.5 teaspoon of olive oil over medium heat for 1 minute until fragrant.
Pour in the chicken bone broth, bring to a boil, then reduce heat to low, cover, and simmer for 15 minutes until the liquid is fully absorbed.
While the rice cooks, season the chicken breast with garlic powder, sea salt, and black pepper.
Heat the remaining 0.5 teaspoon of olive oil in a skillet over medium-high heat and grill the chicken for 6 to 7 minutes per side until cooked through.
Remove the rice from heat, fluff with a fork, and stir in the fresh lemon juice and chopped parsley.
Slice the grilled chicken into strips and serve it over the lemon-herb rice alongside the roasted vegetables.
