This Whole30 grilled fish recipe features a few fresh, bright flavors that make it feel fancy—but it is so simple to prepare. It all starts with a radicchio and grilled pineapple salad tossed in balsamic vinaigrette, which makes for a great base for the meal and tastes both cleansing and sweet. Atop that goes a piece of grilled fish (we used rock cod – a.k.a. Pacific rockfish or Pacific snapper), which is incredibly versatile and mild in flavor. Then, fresh parsley and cilantro come together with lime juice, garlic, olive oil, red wine vinegar, and sea salt for a beautiful chimichurri sauce that ties the whole meal together with a pop of color and citrus. Drizzle (or pour!) as much as your heart desires onto your fish to really turn up that herb-y goodness.

Tips and tricks:

Though this grilled fish meal comes together pretty quickly, you can always simplify the preparation process even more by opting for canned pineapple instead of fresh to minimize the chopping. Just be sure your can lists “pineapple” as the only ingredient, as canned fruits are often packed with sneaky added sugar. Of course, you can also use bagged greens and skip chopping up the radicchio. 

And don’t feel tied to the radicchio if it isn’t your preferred salad green, either. Any variety of lettuce or leafy green will do. (Though, we must say that radicchio’s spice, bitterness, and crunch balance out the sweet, soft grilled pineapple oh so nicely.) That said, you can always get creative with the fruit in your salad, too. Peaches, apricots, and plums are all great seasonal options to incorporate. The same goes for your grilled fish. Other varieties, such as salmon, tilapia, Mahi Mahi, or halibut all sub into this meal seamlessly. 

Finally, though fresh cilantro and parsley are the two herbs typically used in chimichurri sauces, you can mix this one up with whatever other fresh herbs you have handy, like basil or dill. Consider this delightful green sauce your opportunity to use up whatever fresh herbs you have around that might otherwise go to waste!

Whether you’re looking to impress at an evening dinner party with friends and family or just want to spice up your weeknight routine, this simple but elevated Whole30 fish recipe is sure to be a hit.
