Ingredients
To make this bright and zesty tomato, cucumber, and onion salad, you’ll need:
- 4 medium tomatoes (preferably ripe but firm, such as Roma or heirloom)
- 1 large cucumber (English or Persian cucumbers are ideal)
- 1 small red onion (for a sweeter bite)
- ¼ cup fresh parsley or basil, chopped
- 3 tablespoons extra virgin olive oil
- 2 tablespoons red wine vinegar (or lemon juice)
- Salt and black pepper to taste
- Optional: ½ teaspoon dried oregano, a pinch of chili flakes
This salad works beautifully as one of those easy vegetable lunch ideas—quick, satisfying, and adaptable.
Step-by-Step Instructions
Step 1: Prep the Vegetables
Start by washing all your produce thoroughly. Then:
- Tomatoes: Cut into bite-sized wedges or chunks. If they’re very juicy, you may want to remove some seeds to prevent the salad from becoming watery.
- Cucumber: Peel if the skin is tough. Slice into thin rounds or half-moons, depending on your preference.
- Red Onion: Slice very thinly. If you’re sensitive to strong onion flavor, soak the slices in cold water for 10 minutes to mellow them out.
This basic prep lays the foundation for an easy tomato salad that’s crunchy, vibrant, and full of flavor.
Step 2: Make the Dressing
In a small bowl, whisk together:
- 3 tablespoons olive oil
- 2 tablespoons red wine vinegar (or fresh lemon juice)
- Salt and pepper to taste
- Optional: oregano and chili flakes
This vinaigrette echoes Mediterranean flavors and turns the dish into a full-on Italian tomato cucumber salad.
Step 3: Assemble the Salad
In a large bowl, combine the chopped tomatoes, cucumbers, onions, and herbs. Drizzle the dressing over the top and toss gently to coat everything evenly.
Let the salad sit for about 10–15 minutes before serving. This resting time allows the flavors to meld and deepen—a little secret behind the best cold BBQ side dishes for a crowd.
Tips for the Best Salad
- Use fresh, ripe vegetables. The better the quality, the better your salad will taste.
- Slice onions thinly for better texture and balance.
- Salt last-minute if you’re making the salad ahead of time—salt draws out moisture, which could make the salad soggy.
- Chill it for 30 minutes before serving if you want an extra-refreshing dish.
Variations
Want to shake things up? Here are a few ways to customize this recipe for cucumbers and onions:
- Add feta cheese for a Greek-style twist.
- Include olives for more briny depth.
- Swap red onion for sweet white or green onions if desired.
- Add avocado just before serving for creaminess.
- Try balsamic vinegar instead of red wine vinegar for a different flavor profile.
These small changes can transform this simple dish into one of your most flexible and easy fast side dishes.
