Tuna Lime Marinade. Whisk or stir to blend. Step 2 Pour lemon juice over the tuna in the bowl and stir to coat it using a plastic wooden or stainless-steel spoon.

Whisk or stir to blend. Step 4 Place fish on grill rack coated with cooking spray. Squish together until well combined then add tuna steaks. Place tuna in large resealable plastic bag or glass dish.
