Ingredients

Serves 4–6

• 2 large cucumbers, thinly sliced
• 1 pint cherry or grape tomatoes, halved

Helpful Tips for the Best Results

• Salt the cucumbers first: This helps remove excess moisture and keeps the salad from becoming watery.
• Choose firm tomatoes: They hold their shape better after marinating.
• Allow time to marinate: Thirty minutes is enough for great flavor, but a few hours creates an even tastier salad.

How to Make Marinated Cucumbers, Onions, and Tomatoes

1. Prepare the Vegetables

Wash and slice the cucumbers into thin rounds. Cut the tomatoes in half and thinly slice the red onion. If you prefer a milder onion flavor, soak the onion slices in cold water for five minutes, then drain.

2. Remove Excess Moisture

Place the cucumber slices in a colander and sprinkle lightly with salt. Toss gently and allow them to sit for about 10 minutes. Pat dry with paper towels before adding them to the salad.

3. Mix the Dressing

In a large mixing bowl, whisk together the vinegar, olive oil, sugar, salt, and black pepper until well combined and the sweetener has dissolved.

4. Toss and Marinate

Add the cucumbers, tomatoes, and onions to the bowl with the dressing. Gently toss until all the vegetables are evenly coated.

Cover and refrigerate for at least 30 minutes before serving. For deeper flavor, allow the salad to marinate for several hours.

5. Garnish and Serve

Just before serving, stir in your favorite fresh herbs if desired. Serve chilled for the most refreshing flavor.

Serving Ideas

This versatile salad pairs well with many meals, including:

• Grilled burgers and hot dogs
• Barbecue chicken or ribs
• Steak and roasted potatoes
• Sandwiches and wraps
• Fresh bread and cheese platters

For a Mediterranean-inspired variation, add Kalamata olives, crumbled feta cheese, and a sprinkle of oregano.

Storage Tips

• Store leftovers in an airtight container in the refrigerator for up to 2 days.
• The vegetables will continue to soften as they marinate.
• If excess liquid develops, simply drain it before serving.
• For the freshest texture, enjoy within the first 24 hours.
