Many of my lunches are dictated by the spare ingredients we have in the fridge. Today, there was close to a full head of chopped cabbage leftover from garnish for tacos we made the other day. So I sauted it with sesame oil, salt, pepper…and voila…a big plate of cabbage. That certainly wasn’t going to suffice, so I tore open a pouched lemon pepper tuna steak, heated it through, and all of a sudden, had a meal. Super easy and nutritious.

This one steak, which I almost finished, has over 30 grams of protein for just 150 calories. And is jam-packed with omega-3s. A new study found that low omega-3 intake causes about 84,000 U.S. deaths per year. So, as dramatic as it sounds, a couple easy lunches like this a week could literally save lives.
