Store leftovers: If you have any leftovers, cover and refrigerate for up to 2 days. The cucumbers will soften a bit more over time, but the flavors deepen and the salad is still very enjoyable. Stir before serving to redistribute the marinade.
Variations & Tips
For a slightly creamier version that still feels light, whisk in 1–2 tablespoons of full-fat Greek yogurt or sour cream into the marinade, then proceed with the recipe; this often appeals to folks who think they don’t like vinaigrette-based salads. If your household prefers bolder flavors, add 1 small clove of fresh garlic, very finely minced, and a pinch of red pepper flakes to the marinade. To lean into a more Mediterranean direction, swap the dried oregano and basil for 1 teaspoon of dried Italian seasoning, and toss in a handful of crumbled feta cheese and a few sliced Kalamata olives right before serving. For a lower-sugar option, reduce the granulated sugar to 1 tablespoon and compensate with a bit more lemon juice; or use honey instead of sugar for a rounder sweetness. Garden cucumbers can replace English cucumbers—just peel them if the skins are thick and scoop out large seeds. You can also use red onion for more color and a sharper bite, or mix half red onion and half sweet onion. If you want to turn this into more of a main-dish salad, add drained chickpeas, white beans, or cubes of fresh mozzarella. The key is to maintain the balance of crisp cucumber, juicy tomato, and mild onion in a tangy-sweet marinade—that balance is what tends to win over even the salad skeptics.
