Rinse the quinoa under cold water and cook it according to package directions until fluffy.
Preheat your oven to 425°F. Chop the zucchini, red bell pepper, and red onion into bite-sized pieces.
In a bowl, toss the chopped vegetables with olive oil, salt, and pepper. Spread them on a baking sheet and roast for 15-20 minutes until tender and slightly caramelized.
Meanwhile, pat the chicken breast dry. In a small dish, combine the mixed fresh herbs, minced garlic, a pinch of salt, and a dash of black pepper.
Press the herb mixture onto both sides of the chicken breast to form a crust.
Heat a skillet over medium-high heat. Add the chicken and sear for about 4-5 minutes per side until the crust is golden and the chicken is cooked through.
Once all components are ready, plate the quinoa as a base, top with roasted vegetables, and place the herb-crusted chicken on top. Drizzle with lemon juice for added brightness.
Serve immediately and enjoy this balanced, nutrient-rich meal.
