To make this tomato cucumber corn salad, first grill the corn, if using fresh corn on the cob.
There are three basic methods you can use for grilling corn as outlined in the article from Serious Eats about 3 ways to grill corn. I tried all three and prefer the last method below:
- In the husk: When I first starting making grilled corn, I would throw the entire husk on the grill and let it cook. While I loved how the corn turned out, I hated getting the blackened husk all over myself and my kitchen floor.
- Wrapped in foil: Then I tried wrapping the shucked corn in aluminum foil. The corn turned out well, but it was a bit of a chore to check for doneness since I had to unwrap and rewrap the foil packet. Plus the corn didn't get the nice char I was looking for.
- Directly on the grill: So then I decided to shuck the corn and throw it onto the grill. Perfection! The corn looked exactly how I wanted it with a nice smoky flavor. My backyard also smelled like popcorn, which I didn't mind at all.
Once the corn is done cooking and is cool enough to handle, use a knife to remove the kernels. Then you're ready to prepare the salad:
- Combine the tomatoes, cucumbers, corn, and onions in a large bowl.
- Toss with olive oil and balsamic vinegar.
- Season to taste with salt, pepper, and fresh basil leaves, and enjoy!
Tomato Cucumber Corn Salad is wonderful on its own as a light meal or served with any of your favorite dishes. I particularly enjoy it with the following:
- Warm crusty bread like my favorite vegan gluten-free Bread SRSLY sourdough from San Francisco. I mail order it and store it in my freezer. Use code VEGGIESSAVETHEDAY for $5 off your first order.
- Crackers or pita bread and Creamy Sun-Dried Tomato Dip
- Vegan Eggplant Pasta
- Chickpea Veggie Burgers or Cauliflower Curry Grill Packets
- Mediterranean Tofu Tacos
Leftovers will last refrigerated in an airtight container for up to 3 days. The basil may wilt, so you may want to replace it with fresh herbs before serving. I do not recommend freezing this dish.
While there are many methods, including using two bowls or a bundt pan, I find the easiest method is to simply use a chef's knife and a cutting board. Lay the corn on its side horizontally and carefully run your knife down the ear to remove the kernels in sections. When that side is done, rotate the cob and repeat until all of the kernels are removed.
The main ways for cooking corn on the cob are microwaving, boiling, steaming, oven roasting, pressure cooking (in an Instant Pot or other pressure cooker), and grilling. You can also eat corn raw straight off the cob, although many people prefer the flavor and texture of it cooked.
The most common sweet onions available in the United States are Walla Walla, Vidalia, and Maui. These varieties are grown in low-sulfur soil making them taste milder and sweeter than other types of onions.
If your onion has too strong of a taste, slice it and submerge the slices in a bowl of ice water for 20 to 30 minutes before preparing your recipe.
