Begin by partially peeling the cucumbers, leaving some strips of skin intact for added texture. Dice the cucumbers into bite-sized pieces and transfer them to a large mixing bowl.

Next, slice the grape tomatoes into small, bite-sized pieces and add them to the mixing bowl with the cucumbers.

Dice the red onion and toss it into the bowl with the cucumbers and tomatoes.

In a separate mixing bowl, whisk together the red wine vinegar, extra virgin olive oil, minced garlic, Italian seasoning, fresh lemon juice, salt, and black pepper to create the homemade dressing.

Pour the dressing over the cucumber, tomato, and onion mixture, and gently toss everything together until evenly coated.

Cover the salad and refrigerate for at least a couple of hours to allow the flavors to meld together.

Once chilled, give the salad a final toss, taste and adjust seasoning if needed, and serve.
