In a small bowl, whisk together lemon juice, olive oil, and your choice of chopped fresh herbs (such as parsley, basil, or thyme) to create the marinade.
Place the chicken breast in a shallow dish and pour the marinade over it, ensuring it’s well-coated. Let it marinate for at least 20 minutes.
Preheat a grill pan or skillet over medium heat. Grill the chicken for about 6-7 minutes per side, or until fully cooked through.
While the chicken cooks, prepare the base by placing the cooked quinoa in a bowl.
Top the quinoa with a mix of fresh vegetables: cherry tomatoes, cucumber slices, and baby spinach.
Slice the grilled chicken and arrange it over the vegetable and quinoa base.
Drizzle any remaining marinade over the bowl for an extra burst of flavor, and enjoy your balanced, herb-infused meal.
