🥒 Ingredients
For about 4–6 servings, you will need:
- 2 medium cucumbers, thinly sliced (you can peel or leave the skin on, based on preference)
- 2 medium tomatoes, cut into wedges or thick slices
- 1 medium red onion, thinly sliced
- ½ cup white vinegar (or apple cider vinegar for a sweeter flavor)
- ¼ cup water
- 2 tablespoons olive oil
- 1 tablespoon granulated sugar
- 1 teaspoon salt
- ½ teaspoon black pepper
- ¼ teaspoon red pepper flakes (optional, for a slight kick)
- 1 teaspoon dried oregano or Italian seasoning
- Fresh herbs (like chopped parsley, basil, or dill) for garnish
🔪 Preparation Steps
Step 1: Prep the Vegetables
- Cucumbers: Wash them thoroughly. If the skin is thick or waxed, peel it. Slice the cucumbers into thin rounds (or half-moons if large).
- Tomatoes: Choose ripe but firm tomatoes to avoid mushiness. Slice them into wedges or thick slices.
- Onions: Peel and thinly slice the onion into rings. Red onions are preferred for their color and slightly sweeter flavor.
Tip: To reduce the onion’s sharpness, soak the slices in cold water for 5–10 minutes, then drain before mixing
Step 2: Make the Marinade
In a mixing bowl or large measuring cup:
- Combine white vinegar, water, and olive oil.
- Stir in sugar, salt, black pepper, red pepper flakes, and oregano (or seasoning of your choice).
- Whisk the mixture until the sugar and salt fully dissolve.
Optional: Add a splash of lemon juice for added brightness or a crushed garlic clove for more depth
Step 3: Assemble the Salad
- In a large bowl or container with a lid, combine the sliced cucumbers, tomatoes, and onions.
- Pour the marinade over the vegetables, ensuring all slices are coated.
- Gently toss the vegetables to distribute the dressing evenly.
Note: If using a jar or airtight container, shake gently to mix instead of stirring
Step 4: Let It Marinate
- Cover the bowl or container and place it in the refrigerator.
- Let the mixture marinate for at least 2–3 hours, though overnight is ideal for maximum flavor.
- Stir or shake the container occasionally to redistribute the marinade.
🌿 Serving Suggestions
- Serve chilled or at room temperature.
- Garnish with fresh herbs like chopped parsley, basil, or dill for a pop of color and added freshness.
- Pair it with grilled chicken, fish, burgers, or BBQ ribs.
- Add crumbled feta cheese or mozzarella pearls for a Mediterranean twist.
- For a heartier salad, mix in chickpeas or cooked pasta
📦 Storage Tips
- Store leftovers in an airtight container in the refrigerator for up to 4–5 days.
- The vegetables will continue to soften as they sit, so for best texture, consume within the first 2–3 days.
