This is a chopped salad of romaine, cherry tomatoes, cucumber, red onion, Kalamata olives, and crumbled feta, dressed with a lemon-herb vinaigrette made from olive oil, lemon juice, red wine vinegar, Dijon mustard, garlic, and oregano. It takes 20 minutes, uses no heat, and produces four substantial servings. The honest reason to make it: every component is raw and pre-prepped, so the whole thing comes together in the time it takes to chop.
The short version of why this works
The Dijon mustard in the vinaigrette is doing real work here โ it acts as an emulsifier, helping the oil and lemon juice bind into a cohesive dressing that actually clings to the lettuce instead of pooling at the bottom of the bowl. The second thing that matters is the balance between the salty, briny ingredients (olives, feta) and the acidic ones (lemon juice, vinegar). Get that ratio right and the salad seasons itself; tip it too far in either direction and it tastes flat or sharp. Taste the dressing before it goes on, and adjust with a small pinch of salt or an extra squeeze of lemon as needed.
Mistakes to avoid
- Wet lettuce. Romaine holds water in its ribs. If you skip drying it after washing, the dressing gets diluted and the leaves go slick. Spin or pat dry thoroughly before chopping.
- Thick cucumber slices. Half-moons cut too thick turn the salad chewy and hard to fork. Aim for slices no thicker than ยผ inch so they stay light and crisp.
- Raw garlic that overpowers. One clove, minced fine, is the right amount for four servings. If your clove is large, use half. Garlic intensifies as it sits in the dressing, so err on the smaller side.
- Dressing the salad too early. Dress it at the table โ a pre-dressed salad goes limp fast. The romaine starts to wilt within about 15 minutes once the acid hits it.
- Using pre-crumbled feta from a tub. Dry pre-crumbled feta is chalky and doesnโt distribute evenly. Block feta packed in brine is creamier and crumbles into irregular pieces that coat the salad better.
Storage and make-ahead
The dressing keeps well โ store it in a sealed jar in the fridge for up to 3 days and shake before using. The chopped vegetables (tomatoes, cucumber, onion, olives) can be combined and refrigerated in an airtight container for up to 24 hours without losing much texture. Keep the romaine separate in a zip-lock bag with a paper towel to absorb moisture; it stays crisp for a day. Crumble the feta fresh when youโre ready to serve rather than storing it on the salad. Once everything is dressed and assembled, leftovers donโt hold well โ the lettuce softens overnight and the tomatoes release liquid. Plan to dress only what youโll eat in one sitting.
Mediterranean Salad with Lemon-Herb Vinaigrette
Equipment

- Chef's Knife
- Cutting board
- Small whisk or fork
- Measuring spoons

Ingredients
For the Salad:
- 2 cups cherry tomatoes halved, preferably organic and ripe
- 1 cup English cucumber sliced into half-moons
- ยฝ cup red onion thinly sliced
- 1 cup Kalamata olives pitted and halved
- 4 cups romaine lettuce chopped, washed and dried
- 1 cup feta cheese crumbled, preferably block feta in brine
For the Lemon-Herb Vinaigrette:
- ยผ cup extra virgin olive oil use a fruity, cold-pressed variety
- 2 tablespoons fresh lemon juice from about 1 lemon
- 1 teaspoon red wine vinegar
- 1 teaspoon dijon mustard
- 1 clove garlic minced finely
- ยฝ teaspoon dried oregano rub between fingers to release oils
- ยผ teaspoon sea salt more to taste
- ยผ teaspoon black pepper freshly cracked
Instructions
- Start by placing the halved tomatoes, cucumber slices, red onion, halved olives, and chopped lettuce into a large mixing bowl.
- In a small bowl, whisk together the olive oil, lemon juice, red wine vinegar, mustard, minced garlic, oregano, salt, and pepper until emulsified. The vinaigrette should look slightly creamy and well blended.
- Pour the vinaigrette over the salad ingredients just before serving. Gently toss everything to evenly coat, taking care not to mash the tomatoes or feta.

Notes
- For a protein boost, add grilled chicken breast, chickpeas, or tuna chunks.
- Marinating the red onion slices in lemon juice for 10 minutes can mellow their sharpness.
- You can prepare the dressing up to 3 days ahead and keep it sealed in the fridge. Just shake before using.
- Substitute romaine with mixed baby greens or arugula for a peppery twist.

FAQ
Can I use regular cucumbers instead of English cucumber?
Yes, but scoop out the seeds first. Regular cucumbers have a thicker skin and watery seed cavity that can make the salad soggy; halve them lengthwise, scrape out the seeds with a spoon, then slice into half-moons.
Do I have to use romaine, or can I swap in another green?
Romaine works best here because its sturdy ribs hold up against the heavy toppings and bold dressing without wilting immediately. Baby spinach or chopped iceberg are reasonable substitutes; arugula works too but adds a peppery bite that competes with the red onion.
My dressing separated โ is it ruined?
No, just whisk or shake it again before pouring. Oil and water-based ingredients always separate on standing; the Dijon helps them re-emulsify quickly with a few seconds of agitation.
Can I make this salad for a crowd and double the recipe?
Doubling is straightforward โ all the ingredients scale evenly. The one thing to watch is the garlic in the dressing: doubling to two cloves can make it sharp, so taste as you go and stop at one and a half cloves if the garlic flavor feels strong.
