There are so many things to look forward to in the summer. Aside from lazy beach days, sunny skies, warm temps and family vacations, summer is the best time (in my opinion) for good eating – especially good eats made on the grill and eaten on the deck or good eats packed for a sunset beach picnic. Fresh, bright, light flavors abound that are so simple, yet over-the-top delicious. Juicy summer garden tomatoes sprinkled with sea salt. Summer herbs like dill, basil and cilantro tossed into salads and overtop summer dishes. Sweet summer corn on the cob grilled and rubbed with butter. All of these simple dishes are pure summer perfection.

This Grilled Corn with Walnut Pesto simple side dish is the perfect summer dish taken up a notch. It’s one of our favorite summer recipes because it celebrates sweet corn on the cob by slathering it in a bright, garlickly, nutty green pesto made with basil, parsley, garlic, California walnuts, parmesan cheese, lemon and extra virgin olive oil. This easy pesto comes together in just minutes in the food processor. Note: Make extra pesto because you’ll want to slather it on everything – like tomato and mozzarella stacks, grilled eggplant and zucchini, grilled white fish, grilled chicken or tossed it with pasta.

You’ll top the pesto slathered corn with some additional chopped walnuts. Walnuts are the perfect ingredient for summertime recipes prepared on the grill, adding both a mild, nutty flavor and a delightful crunch. The rich walnuts pair really nicely with the sweet corn on the cob and the bright, garlicky pesto.

We love adding versatile and heart-smart walnuts to summer dishes – especially appetizers (fruit and cheese platters, summer dips) salads (greens or grain based) and grilled fruit desserts (grilled peaches, plums, nectarines and pineapple).

What’s your favorite way to use walnuts in the summer? Have you tried them in pesto?

Did you know? Not all nuts contain omega-3s and walnuts are the only nut to contain a significant amount of alpha-linolenic acid (ALA), the essential plant-based omega-3 fatty acid. In one ounce, there are 2.5 grams of ALA, which is more than five times the amount found in any other nut.
