Making this salad is a truly enjoyable process, especially when you're working with peak season produce. It’s a very simple recipe, yet the result is incredibly satisfying. You'll find that the steps are quite intuitive, allowing you to create a beautiful and flavorful dish with very little effort. It’s about letting the natural goodness of the ingredients shine through, you know, with just a little help from a bright dressing.

Gathering Your Fresh Produce

To start, you’ll want to pick the freshest cucumbers, tomatoes, and onions you can find. For cucumbers, aim for firm ones without soft spots, and for tomatoes, look for ones that are heavy for their size and have a pleasant, earthy scent. Red onions should be firm and free of blemishes. Once you have your produce, give everything a good wash under cool running water. This ensures you're starting with clean, crisp ingredients, which is pretty important for any fresh salad.

A little tip for the onions, if you find them a bit too strong: after slicing, you can give them a quick rinse under cold water. This helps to mellow their sharpness without taking away their flavor. Some people even like to soak them in ice water for a few minutes. It’s a small step, but it can make a difference in the overall balance of the salad, especially if you're sensitive to strong onion flavors. You're aiming for a pleasant bite, not an overwhelming one, so that's something to consider.

The Magic of the Marinade

The secret lies in the marinade, which transforms simple vegetables into something truly special. This isn't just a dressing; it's a quick bath that infuses everything with sweet and tangy notes. In this recipe for cucumber, tomato, and onion salad, we're using a red wine vinegar dressing and herbs to bring everything together. Red wine vinegar offers a lovely depth, a little bit fruity and a little bit sharp, which really wakes up the flavors of the vegetables.

To make the marinade, you’ll typically combine sugar, water, vinegar, oil, and dried herbs. Some recipes might even call for a touch of seasoned rice vinegar, which can add a nice, subtle sweetness and tang. You could also use olive oil, or perhaps a blend of oils, depending on your preference. The dried herbs, like a little bit of oregano or dill, really round out the flavor profile, giving it that classic, comforting taste. It’s the kind of dressing that you’ll want to have on hand for other salads, too, it’s that good.

Step-by-Step Assembly

Putting this salad together is a breeze. First, you'll want to prepare your vegetables. Slice your cucumbers into nice, even rounds or half-moons, depending on their size. Chop your tomatoes into bite-sized pieces, letting their juices collect. For the onion, thin slices are best, allowing them to disperse evenly throughout the salad. In a large bowl, add sliced tomatoes, cucumbers, and onions. It’s quite a colorful sight, honestly, all those reds and greens.

Next, you’ll work on that delightful marinade. In a small mixing bowl, mix seasoned rice vinegar, olive oil, and Lawry's seasoned salt, if you're going for that specific flavor profile. Or, you might combine your red wine vinegar, water, sugar, and dried herbs. Whisk it all together until the sugar dissolves completely. This ensures that every bite gets that perfect balance of sweet and tangy. It’s pretty straightforward, and you'll see how quickly it comes together.

Now, for a crucial step, especially if you're using red onions: some recipes suggest a quick marination for the onions themselves. You can combine chopped cucumber and sliced red onion in a bowl, sprinkle with kosher salt and toss to combine. Let sit for 20 minutes, then pour off any liquid from the bowl. This helps to draw out some of the excess moisture from the cucumbers and mellows the onions even further. After this, you simply add sliced onions, chopped tomatoes, sliced cucumbers, sugar, water, vinegar, oil, dried herbs into a large bowl and mix well. Some people like to marinate the onions in a bowl with the salt, oil, and vinegar first. After 5 to 10 minutes, you then add tomatoes with their juices and cucumbers, stir in the remaining oil, and season. Whichever method you choose, the goal is to get all those wonderful flavors mingling together.
