2 large English cucumbers
4-5 ripe Roma tomatoes
1 medium red onion
2 cloves garlic, minced
1/2 cup extra virgin olive oil

2 tablespoons granulated sugar
1 teaspoon dried dill (or 2 tbsp fresh, chopped)
1/2 teaspoon salt
1/4 teaspoon black pepper
Fresh parsley or dill (for garnish, optional)

Step-by-Step: How to Make Easy Marinated Cucumber Tomato Onion Salad

1. Prepare Vegetables

Wash and slice 2 large English cucumbers into 1/4-inch half-moons. Rinse, core, and cut 4-5 Roma tomatoes into bite-sized wedges. Peel and thinly slice 1 medium red onion. Finely mince 2 cloves garlic.

2. Make Marinade

In a medium bowl, whisk together 1/2 cup extra virgin olive oil, 1/4 cup apple cider vinegar, 2 tbsp granulated sugar, 1 tsp dried dill, 1/2 tsp salt, 1/4 tsp black pepper, and the minced garlic until sugar dissolves. Taste and adjust seasoning as desired.

3. Combine & Marinate

Place prepared cucumbers, tomatoes, and onion in a large mixing bowl. Pour marinade over vegetables and toss gently to coat evenly. Cover the bowl tightly with plastic wrap or transfer to an airtight container.

4. Chill

Refrigerate for at least 2-4 hours, or preferably overnight, to allow flavors to deepen and meld. If marinating for an extended period, give it a gentle stir halfway through.

5. Serve

Give the salad one final gentle stir. Transfer to a serving bowl and garnish with fresh parsley or additional fresh dill, if desired. Serve chilled. Store leftovers in an airtight container in the refrigerator for up to 3-4 days.
