Steps
1. In a bowl, combine olive oil, lemon juice, oregano, thyme, minced garlic, salt, and pepper.
2. Add the chicken breast to the marinade and coat evenly. Let it marinate for at least 30 minutes.
3. Preheat the grill or a grill pan over medium heat.
4. Grill the chicken for 6-7 minutes on each side, or until fully cooked and the juices run clear.
5. While the chicken is grilling, steam the mixed vegetables until tender.
6. Serve the grilled chicken alongside the steamed vegetables, garnished with a slice of lemon if desired.
