 Ingredients

For the Salad

2 large English cucumbers, thinly sliced

1 medium red onion, thinly sliced

2 cloves garlic, minced

¼ cup fresh parsley, chopped

2 tablespoons fresh cilantro, chopped (optional)

½ teaspoon red pepper flakes (optional)

½ teaspoon salt

½ teaspoon black pepper

For the Dressing

¼ cup extra virgin olive oil

3 tablespoons fresh lemon juice or apple cider vinegar

1 tablespoon honey

1 teaspoon Dijon mustard

½ teaspoon dried oregano

 Instructions

Step 1: Prepare the Vegetables

Wash the cucumbers thoroughly and slice them into thin, even rounds. Thinly slice the red onion and mince the garlic. Chop the parsley and cilantro if using.

Step 2: Combine the Salad

Place the cucumbers, red onion, garlic, parsley, cilantro, red pepper flakes, salt, and black pepper into a large bowl or a clean glass jar.

Step 3: Make the Dressing

In a small bowl or measuring cup, whisk together the olive oil, lemon juice (or apple cider vinegar), honey, Dijon mustard, and dried oregano until smooth and well combined.

Step 4: Dress the Salad

Pour the dressing over the cucumber mixture. Toss everything gently until the vegetables are evenly coated.

Step 5: Marinate

Cover the bowl or seal the jar and refrigerate for at least 30 minutes. For the best flavor, let it marinate for 1–2 hours, stirring or shaking the jar occasionally.

Step 6: Serve

Give the salad a final toss before serving. Garnish with extra parsley, cracked black pepper, or a sprinkle of red pepper flakes if desired.
