Preheat your oven to 425°F. Line a baking sheet with parchment paper.
Season the chicken breast with garlic powder, salt, and pepper. Lay it on the baking sheet and lightly spray with olive oil if desired for extra crispiness.
Place the chicken in the oven and bake for 18-20 minutes or until cooked through. For extra crispiness, you can broil for an additional 2 minutes if needed.
While the chicken bakes, chop the zucchini, red bell pepper, and red onion into bite-sized pieces. Toss them with olive oil, salt, and pepper, and spread them evenly on another baking sheet.
Roast the vegetables in the oven for about 15-18 minutes until they are tender and slightly caramelized, stirring halfway through.
In a small bowl, whisk together tahini, lemon juice, a splash of water to achieve the desired consistency, and a pinch of salt. Adjust flavor as needed.
Slice the baked chicken into strips or bite-sized pieces. Assemble your bowl by layering the roasted vegetables and chicken. Drizzle generously with the creamy tahini dressing.
Enjoy your balanced, crispy chicken and roasted vegetable bowl as a nourishing meal for breakfast, lunch, or dinner.
