Step 1

Combine your marinade in a small bowl.

Step 2

Season your tuna steaks with salt and pepper and then place them in a ziplock bag. Pour the marinade in and allow it to sit for 15-25 minutes. You do not want it to marinade any longer since the vinegar can begin to “cook” the tuna like in ceviche.

Step 3

Coat them with the sesame seeds.

Step 4

Turn your grill on high. Generously spray the grill with non sticking cooking spray. Place your steaks on the grill to sear for 2-3 minutes per side. It should be crispy on the outside and bright pink on the inside.
