Preheat your oven to 400°F.
Season the chicken breast with mixed herbs, a splash of olive oil, lemon juice, salt, and pepper.
Place the chicken breast on a baking sheet and roast for about 20-25 minutes, or until the internal temperature reaches 165°F.
While the chicken is cooking, prepare the quinoa as per package instructions if not pre-cooked.
In a bowl, combine the cooked quinoa, cherry tomatoes, diced cucumber, and baby spinach.
Once the chicken is done, slice it into strips and add on top of the quinoa and veggie mix.
Gently fold in the avocado pieces and drizzle with any remaining lemon juice or olive oil if desired.
Serve warm and enjoy your balanced, herb-infused bowl.
