A perfectly seasoned tuna steak that makes an ideal Weight Watchers lunch or dinner recipe, this Seared Ahi Tuna is absolutely delicious.

It’s packed with healthy fat and protein and works wonderfully over a salad or rice. It also cooks really fast, so this is something you can get on the plate quickly.

I actually prefer mine a little more undercooked, but since my kids were eating this dish too, I opted to cook it a little longer, as you can see in the photo. But the delicious ginger and soy flavors balance the the delicate tuna perfectly, without overwhelming it.

This is definitely an easy fish recipe that tastes great, can be prepared by anyone, and is low in Points.
