Slice the cucumbers into thin, even rounds and arrange them in a large mixing bowl.
Chop the tomatoes into bite-sized chunks and add them to the bowl with the cucumbers.
Scatter the cheese cubes or crumbles over the vegetables, distributing evenly.
In a small bowl, whisk together olive oil, lemon zest, minced garlic, and chopped basil until the mixture is fragrant and slightly emulsified.
Pour the basil lemon oil over the salad, tossing gently to coat all the ingredients evenly.
Drizzle the balsamic vinegar over the top, adding a glossy shimmer to the salad.
Season with salt and freshly ground pepper to taste, then give everything one last gentle toss.
Serve immediately in a large bowl or individual plates, enjoying the fresh crunch and vibrant colors.
