Marinated Cucumbers, Onions, and Tomatoes
Ingredients:
For the Vegetables:
Ingredient Quantity
Medium cucumbers, thinly sliced 2
Large tomato, diced 1
Red onion, thinly sliced 1/2
Fresh parsley or dill, chopped A handful (optional)
For the Marinade:
Ingredient Quantity
Olive oil 3 tablespoons
Red wine vinegar (or apple cider vinegar) 2 tablespoons
Honey or sugar 1 teaspoon (optional, for balance)
Salt To taste
Pepper To taste
Dried oregano 1/4 teaspoon (or 1 tsp fresh, minced)
Red pepper flakes Pinch (optional, for heat)
Instructions:

Step 1: Prepare the Vegetables Wash the 2 medium cucumbers and slice them thinly using a sharp knife or a mandoline slicer for consistent, even cuts. Dice the 1 large tomato into small, uniform pieces to ensure it marinates evenly and doesn’t overpower the other vegetables. Slice the 1/2 red onion thinly. For extra precision and to mellow its sharpness, you can use a mandoline. To further reduce the onion’s pungent bite, soak the sliced onions in a bowl of cold water for 5–10 minutes, then drain thoroughly and pat them dry with a paper towel.
Step 2: Combine the Ingredients In a large mixing bowl, combine the prepared cucumbers, tomatoes, and onions. If you are using fresh herbs like parsley or dill, sprinkle them over the vegetables now.

Step 3: Make the Marinade In a separate small bowl, whisk together the 3 tablespoons olive oil, 2 tablespoons red wine vinegar (or apple cider vinegar), 1 teaspoon honey or sugar (if using), salt, pepper, 1/4 teaspoon dried oregano (or 1 tsp fresh, minced), and a pinch of red pepper flakes (optional) until all ingredients are well combined and the honey/sugar has dissolved. Taste the marinade and adjust seasonings as needed to suit your preference.
Step 4: Marinate the Mixture Pour the prepared marinade over the vegetable mixture in the large bowl. Gently toss the vegetables to coat them evenly with the marinade, being careful not to bruise the delicate slices of cucumber and tomato.
Step 5: Chill Before Serving Cover the bowl with plastic wrap and refrigerate for at least 30 minutes. This chilling period is crucial as it allows the flavors to meld together and deepen, resulting in a more harmonious and refreshing salad. For an even richer flavor, you can let it marinate for up to 2 hours.
Step 6: Serve & Enjoy Spoon the marinated cucumbers, onions, and tomatoes into individual bowls or onto plates. Garnish with additional fresh herbs, if desired, for a pop of color and extra freshness. Serve chilled or at room temperature.

Tips for Success
Use Fresh Produce: The quality of your ingredients truly shines in this simple salad. Choose firm, crisp cucumbers, ripe, flavorful tomatoes, and fresh, crisp onions for the best texture and taste.
Adjust Spices: This recipe is highly customizable. Feel free to increase or decrease the amount of red pepper flakes based on your preference for heat. You can also experiment with other dried herbs like basil or a touch of garlic powder.
Experiment with Herbs: While parsley and dill are classic choices, don’t hesitate to swap them out for other fresh herbs like mint or basil for a different flavor twist that complements the fresh vegetables and tangy dressing.
Make It Vegan: If you’re looking for a plant-based option, simply skip the honey and use an equal amount of maple syrup or agave nectar instead. The subtle sweetness will still balance the acidity of the vinegar.
