How to Make Marinated Cucumbers, Onions, and Tomatoes
1. Prepare the Vegetables
Wash the cucumbers and tomatoes well. Slice the cucumbers into thin rounds, cut the tomatoes into wedges, and thinly slice the red onion.
Place all the vegetables into a large bowl.
2. Make the Marinade
In a separate bowl, whisk together the olive oil, apple cider vinegar, water, sugar, salt, black pepper, oregano, and minced garlic.
Continue whisking until the ingredients are well combined.
3. Combine the Salad
Pour the marinade over the cucumbers, tomatoes, and onions.
Gently toss everything together so the vegetables are evenly coated.
4. Let It Marinate
Cover the bowl and refrigerate for at least 1 hour.
For even more flavor, you can let the salad chill for a few hours. As it rests, the vegetables absorb the tangy marinade while the tomatoes release some of their natural juices.
5. Garnish and Serve
Give the salad a gentle toss before serving and sprinkle with fresh parsley.
Serve chilled alongside your favorite meal.
