Tip, Trick & a Recipe: Firm White Fish

Many Dinner Answers subscribers have asked, “What is firm white fish?” I’ve been using that term for years without thinking twice about how everyone might not know what I mean. I always want to give you the option to choose and if I mention “firm white fish” there are quite a few options (think tilapia, halibut and cod for example), but this time I’m going to focus on Mahi Mahi.

Mahi Mahi is a lean protein chock full of omega-3s and vitamin B12, two nutrients that will keep your mind sharp and your body lean. Even if you don’t like fish I encourage you to keep trying different types and recipes until you find something you enjoy – I promise there’s a strong chance you’ll find something!

Here’s your Tip:

If you’re grilling Mahi Mahi, use a marinade! It’ll add a lot of scrumptious flavor and prevent the filets from getting charred (charred food can lead to cancer). Toss the marinade the fish has marinated in–this isn’t good for anything anymore…it’s done its job.

Here’s your Trick:

Toss some summer veggies on the grill in the same marinade (not the stuff the fish was in; make extra)! I recommend summer squash, zucchini, onions, and always garlic! Quick and easy portion of veggies!
