Easy and delicious, this quick, healthy side dish will dress up every meal!


Summer has always been my favorite season. I love the variety and availability of nutrient-rich produce, typically fresher and tastier this time of year. Local grocers and farmer’s markets burst with abundant fresh, whole foods such as fruits and vegetables. Now is the perfect time to try out the season’s best produce for dishing up delicious summer side dishes for your family or when entertaining friends.

Here is a delightful summer side dish sure to be a crowd-pleaser making summer eating a breeze. Some of the most iconic summer veggie favorites are found in this recipe, lightly seasoned with a compelling, fresh, and tasteful chili-lime vinaigrette. In addition, this simple and flavorful side is loaded with various nutrients supporting good health.

I used summer squashes of zucchini and yellow squash, corn, and edamame for this recipe. Here’s  a brief nutritional look at each one:


There’s a good chance you either have summer squash growing in your garden or know someone who does. Walk into any grocery store, and there are several types of summer squash available. The most common types in the U.S. are the familiar and prolific zucchini and yellow squash.

Both summer squash types are versatile additions to meals with almost no fat.  Naturally low calorie, a good source of fiber, and rich in beta-carotene, summer squash’s health benefits include possibly warding off cancers, and heart disease and protecting your vision with age.


Corn is a “starchy” food, but you must remember that each corn kernel you eat is a seed. For a seed to germinate and grow, energy in the form of sugar packed in each kernel that, if planted, is required for it to grow into a tall corn stalk.  Does that mean the only thing corn offers is a lot of starch and sugar?  No – those kernels are also packed with a bevy of nutrition:

  • Corn is a good source of thiamin, folate, and vitamin C. It also provides trace minerals such as selenium which can be challenging to find in most normal diets.
  • Corn also provides numerous phytochemicals, including lutein and zeaxanthin – antioxidants linked to eye, heart, and skin health.
  • One cup of corn provides about 4 grams of fiber which can aid in reducing digestive problems of constipation and hemorrhoids.


More appealing than tofu or tempeh, edamame resembles a lima bean but has a more pleasing taste and texture.  Edamame is an immature green soybean and is considered the second most popular soy food in America after soymilk.

Sometimes edamame will be labeled as “mukimama,” which is the Japanese term for edamame shelled from the pod.  Most U.S. grocery stores will usually have the packages marked as “shelled edamame.” Look for edamame in the frozen vegetable section of your grocery store.

When it comes to nutritional exceptionality, edamame is tough to beat.  Nutrient-packed, it is considered a standout even among other soy foods.  One cup of edamame contains just under 200 calories, 8 grams of fiber, and 18 grams of complete protein.  Edamame is also well-balanced in terms of its macronutrient makeup – about one-third of the calories in edamame come from protein, one-third from carbohydrates, and one-third from fat.  This balanced ratio of macronutrients makes edamame a winner in terms of being a perfect snack providing the right balance of protein, carbs, and fat plus fiber to increase satiety.


You’ll agree that one taste of this dish says “summer” with every bite. The variety of textures, flavors, and the chili-lime vinaigrette is just the right blend of ingredients reminiscent of a summer cookout and will pair well with anything hot off the grill. This dish also comes in handy for gardeners for using up an abundance of late summer produce of zucchini, yellow squash, corn, and cherry tomatoes.

This recipe can easily be doubled (or tripled) and is perfect for a summer cookout! You can also get creative by adding in other ingredients such as feta cheese, red onion, a finely chopped jalapeno (for a fiery burst of flavor), or other fresh herbs in addition to cilantro.
