Ingredients

  • 2 tablespoons extra-virgin olive oil
  • 2 tablespoons red wine vinegar or lemon juice

  • ¼ teaspoon black pepper, freshly ground
  • Fresh herbs (optional): parsley, basil, or dill, chopped

Instructions

You Must Know

  • Marinating the salad helps the flavors blend and improves the taste.
  • Use firm, ripe tomatoes and crisp cucumbers for best texture.
  • If the onion flavor is too strong, soak the sliced onion in cold water for a few minutes before draining and adding.

Storage Tips

  • Store any leftovers in an airtight container in the fridge for up to 2 days.
  • Stir before serving again — the vegetables may release some liquid.

Ingredient Substitutions

  • Swap red wine vinegar with apple cider vinegar, lemon juice, or white wine vinegar.
  • Use honey or maple syrup instead of sugar for a different type of sweetness.
  • Add extra veggies like bell peppers, radishes, or avocado.
  • For a salty twist, mix in crumbled feta or small mozzarella balls.

Serving Suggestions

  • Pair with grilled meats, fish, or kebabs.
  • Serve over rice or quinoa for a light vegetable bowl.
  • Use as a topping for grilled bread or bruschetta.

Pro Tips

  • Cut vegetables to similar sizes to make sure flavors are consistent and well-balanced.
  • Whisk the vinaigrette well to emulsify the oil and vinegar.
  • Taste and adjust the dressing at the end — acidity and saltiness can mellow after marinating.

Frequently Asked Questions

→ Can I make this salad ahead?
Yes — you can prepare it a few hours before serving and keep it chilled.

→ Will the vegetables get soggy?
They’ll soften over time, so it’s best enjoyed within a day or two.

→ Can I add cheese?
Absolutely — feta, goat cheese, or mozzarella all pair beautifully with these flavors.
