- 2 tablespoons fresh dill (optional, but highly recommended)

How to Make Marinated Cucumber Tomato Salad
Step 1: Prepare the Vegetables
- Slice cucumbers into ¼-inch rounds (peel partially or leave skin on)
- Cut tomatoes into wedges or chunks (halve cherry tomatoes if using)
- Thinly slice the red onion into half-moons
- Chop parsley and dill
š” Pro Tip: Lightly salt the cucumbers and let them sit for 15 minutes, then pat dry. This removes excess moisture and keeps your salad crisp—not watery.
Step 2: Make the Vinaigrette
In a small bowl or jar, combine:
- Red wine vinegar
- Olive oil
- Garlic
- Oregano
- Sugar
- Salt and pepper
Whisk or shake until fully blended.
Step 3: Toss Everything Together
In a large bowl, combine:
- Cucumbers
- Tomatoes
- Onion
- Parsley
- Dill (if using)
Pour the vinaigrette over the vegetables and gently toss to coat.
Step 4: Let It Marinate
Allow the salad to sit for at least 30 minutes at room temperature, or refrigerate for up to 4 hours.
This step is key—it helps the vegetables soak up all that delicious flavor.
Step 5: Serve
Give the salad a quick toss before serving. Enjoy it chilled or at room temperature.
