Preheat your grill or grill pan over medium-high heat.
Season the chicken breast with salt, pepper, and a drizzle of olive oil. Allow it to marinate briefly while you prepare the quinoa and zucchini.
Rinse the quinoa under cold water. In a small pot, combine the rinsed quinoa with water (use the recommended ratio) and a pinch of salt. Bring to a boil, then reduce heat and simmer until the quinoa is fluffy and water is absorbed. Once cooked, mix in the chopped fresh herbs and lemon juice.
Slice the zucchini lengthwise into thick strips. Toss with a bit of olive oil, salt, and pepper. Roast the zucchini in an oven preheated to 425°F (220°C) for about 15-20 minutes until tender and slightly caramelized, or grill alongside the chicken if preferred.
Grill the chicken breast for about 5-6 minutes per side, or until the internal temperature reaches 165°F (74°C).
Slice the avocado and lightly mash with a pinch of salt to create a drizzle or spread.
Assemble the plate by placing a serving of herbed quinoa, then top with the grilled chicken and arrange the roasted zucchini on the side. Drizzle the mashed avocado over the zucchini for an added creamy element.
Serve immediately and enjoy this balanced Mediterranean-inspired dinner.
