Steps
1. In a small bowl, whisk together olive oil, lemon juice, parsley, dill, garlic, salt, and pepper.
2. Place the tuna steak in a shallow dish and pour the marinade over it, ensuring it's well coated. Let it marinate for at least 15 minutes.
3. Preheat the grill or a grill pan over medium-high heat.
4. Remove the tuna from the marinade and grill for about 2-3 minutes on each side for medium-rare, adjusting the time based on your preferred doneness.
5. Remove from the grill and let it rest for a minute before slicing.
6. Serve with lemon wedges on the side.
