Fresh dill is my favorite herb for this salad because it reminds me of the ones my grandmother used to grow We would pick the dill together in her garden and sprinkle it over the finished dish before serving It is a memory that always brings me back to summer days spent with family

Keep leftovers covered in the refrigerator They stay fresh for up to two days The cucumbers may lose a little crunch after a while but the flavors deepen as they sit If you want even more texture add a handful of diced fresh cucumber before serving

Ingredient Substitutions

If you do not have cherry tomatoes you can use any ripe tomato chopped into bite size pieces White onion offers a milder taste but red onion gives a vibrant color Fresh basil mint or cilantro can step in for parsley or dill and each will give a unique twist to the salad A touch of lemon zest also brightens up the vinaigrette
