Ingredients Overview

Cucumbers: Choose fresh, crisp cucumbers like English or Persian varieties for the best texture.
Tomatoes: Use ripe and juicy tomatoes, such as cherry tomatoes or vine-ripened varieties.
Onions: Red onions are ideal for their mild, sweet flavor, but white onions can also work.
Vinegar: Adds a tangy kick to the marinade; white or apple cider vinegar works well.
Oil: A neutral oil like olive oil balances the tang and adds a silky finish.
Herbs & Spices: Fresh dill or parsley adds brightness, while salt and pepper enhance the flavors.

Ingredients

2 large cucumbers, thinly sliced
4 medium tomatoes, cut into wedges or sliced
1 medium red onion, thinly sliced
½ cup white vinegar or apple cider vinegar
¼ cup olive oil
2 tablespoons granulated sugar (optional, for a touch of sweetness)
1 teaspoon salt
½ teaspoon black pepper
1 teaspoon dried oregano or fresh dill (optional)

Step-by-Step Instructions

1. Prepare the Vegetables

Wash the cucumbers, tomatoes, and onion.
Slice the cucumbers thinly, cut the tomatoes into wedges or slices, and thinly slice the onion. Place them in a large mixing bowl.

2. Make the Marinade

In a small bowl, whisk together the vinegar, olive oil, sugar (if using), salt, pepper, and oregano or dill until well combined.

3. Combine and Marinate

Pour the marinade over the vegetables in the mixing bowl. Toss gently to coat all the vegetables evenly.
Cover and refrigerate for at least 1 hour to let the flavors meld. For the best flavor, marinate for 2-3 hours or overnight.

4. Serve

Stir the vegetables before serving to redistribute the marinade. Serve chilled as a side dish or salad.
