Preheat your grill to medium-high heat.
In a bowl, mix olive oil, garlic powder, onion powder, paprika, oregano, salt, and pepper.
Coat the chicken breasts evenly with the marinade.
Let the chicken marinate for at least 15 minutes.
Place the chicken on the grill, and cook for 5-7 minutes on one side.
Flip the chicken and grill for another 5-7 minutes, checking for doneness.
Use a meat thermometer to ensure the internal temperature reaches 165°F (75°C).
Once cooked, remove the chicken from the grill and let it rest for 5 minutes.
Garnish with fresh herbs before serving.
Serve with your favorite sides.
