Ingredients

Scale
  • 2 cucumbers, sliced

  • 1 red onion, thinly sliced

  • 2 cups cherry tomatoes, halved

  • 1/4 cup apple cider vinegar

  • 2 tablespoons extra virgin olive oil

  • 1 teaspoon sugar

  • 1 teaspoon kosher salt

  • 1/2 teaspoon freshly cracked black pepper

  • 1 clove garlic, minced

  • 1 teaspoon dried oregano

  • 1/4 cup fresh parsley or basil, chopped (optional for garnish)


Instructions

  • Slice the cucumbers into 1/8-inch thick rounds and the red onion into thin half-moons. Halve the cherry tomatoes.

  • In a large bowl, combine the cucumbers, onions, and tomatoes.

  • In a separate bowl, whisk together the apple cider vinegar, olive oil, sugar, salt, pepper, garlic, and oregano until well combined.

  • Pour the marinade over the vegetables, stirring gently to coat them evenly.

  • Cover the bowl with plastic wrap or a lid and refrigerate for at least 1 hour (3-4 hours is ideal for the best flavor).

  • Just before serving, garnish with fresh parsley or basil for a burst of color and extra freshness.

  • Serve cold and enjoy the refreshing flavors!

Notes

  • For an extra kick, add a pinch of red pepper flakes to the marinade.

  • If you want to make this dish ahead of time, it improves with sitting in the fridge for up to 24 hours, so it’s great for meal prep or potlucks.

  • You can also substitute the apple cider vinegar with white wine vinegar or rice vinegar for a slightly different flavor profile.
