Storage Instructions

– Store in an airtight container in the fridge for up to 2 days. – If making ahead, keep the dressing separate and toss right before serving to maintain crunch. – Refresh leftovers with a squeeze of lemon and a pinch of salt. – Avoid freezing; the vegetables will turn soft and watery.

What Not to Do

Don’t skip salting the veggies. It prevents a watery salad. – Don’t overdress. Add dressing gradually; you can always add more. – Don’t use dull herbs. Wilted herbs mute the flavor—fresh is best. – Don’t make it too far ahead. More than a day in advance can soften the cucumbers and tomatoes.

FAQ

Can I use regular cucumbers instead of English or Persian?

Yes. Peel them if the skin is thick and scoop out large seeds to avoid excess water.

Slice thinly and follow the salting step.

What tomatoes are best for this salad?

Ripe cherry or grape tomatoes hold their shape well and stay sweet. In peak season, heirlooms or vine tomatoes are great—just seed them if very juicy.

How can I make this ahead without it getting soggy?

Prep the veggies and dressing separately. Assemble and dress 30 minutes before serving so the salad stays crisp.

Is there a substitute for red wine vinegar?

White wine vinegar or extra lemon juice works.

Balsamic changes the flavor profile but can be delicious with basil and mozzarella.

What can I serve with it?

Grilled chicken, shrimp, or steak, crusty bread, or a pasta bake. For a cozy pairing that travels well, try this Cottage Cheese Protein Pasta Bake.
