Make Tomato Cucumber Salad quickly: a bright, crunchy salad ready in minutes — perfect for summer sides and easy gatherings.
Gently place the glossy halved cherry tomatoes and the crisp 1/4" cucumber coins into a clear round mixing bowl. Let the vivid reds and bright greens nestle together — this is where the salad’s color story begins. Keep the tomatoes slightly tilted so their juicy interiors face up, and arrange cucumber slices in a loose, overlapping pattern so each piece stays visible and texturally distinct.
Drizzle 3 teaspoons of olive oil and 1 teaspoon of red wine vinegar over the vegetables, then sprinkle salt and freshly ground black pepper to taste. Use a light hand so the dressing sits as a glossy sheen on the tomato cut surfaces and beads on the cucumber edges; the goal is a thin, even coating that highlights texture rather than drowns it.

Using a pair of salad servers or a gentle folding motion, toss the salad so every tomato half and cucumber coin gets a touch of oil, vinegar, salt, and pepper. Aim for a loose, airy toss — you want to avoid bruising the tomatoes while ensuring the dressing clings to the surfaces. The result should read as uniformly dressed, with tiny droplets of oil catching the light across the bowl.
Scatter 2 tablespoons of finely diced red onion over the top for a crisp, purple contrast, then finish with 2 tablespoons of freshly chopped basil leaves, torn slightly so the aromatic oils release. Give the bowl one final gentle lift to settle the garnish, then serve immediately so the textures stay bright and the basil remains vibrant.
