Step 5

Storage Options
Store any leftovers in an airtight container in the refrigerator for up to 48 hours. Although fresh is best, you can refresh the salad by adding extra basil or a splash of vinegar before serving. This salad is not ideal for freezing, as the tomatoes can become mushy when defrosted.
Variations & Substitutions
For a twist, consider adding crumbled feta or mozzarella pearls to enhance the creaminess of the salad. If you’re catering to a vegan crowd, remove the dairy elements and add avocado for a creamier texture. You can also experiment with different herbs, like mint or cilantro, for an exciting flavor profile.
Serving Suggestions
Enjoy this salad on its own or as a side dish with grilled meats or fish. It’s a wonderful addition to a summer buffet or served at picnics and barbecues. For an elegant presentation, serve it on a platter with a few whole basil leaves as garnish, emphasizing the fresh ingredients.
Frequently Asked Questions
Can I make this salad ahead of time? Yes, this salad can be made a few hours in advance. Store it in the fridge until required, but add the basil just before serving to maintain its freshness and vibrancy.
What other dressings can I use? While the classic olive oil and vinegar dressing is a staple, you can use balsamic vinaigrette for a sweeter punch or lemon juice for a zesty twist.
How can I cut down the sharpness of the onions? To mellow down the sharpness of raw onions, soak them in cold water for about 10 minutes before adding them to the salad. This method helps remove some of the pungency while keeping them crisp and tasty.
