To keep this salad keto friendly, measure the chickpeas carefully and resist adding extra, since they are included only as a small texture accent. For the best texture, use firm English cucumbers and pat them dry if very juicy before chopping, which helps prevent a watery salad. Block feta in brine has superior flavor and texture compared to pre crumbled feta and holds its shape better when tossed. If making the salad ahead, store the chopped cucumbers, feta, chickpeas, and herbs separately from the dressing and combine them just before serving. The finished salad is best within 1 day but can be stored in an airtight container in the refrigerator for up to 2 days, understanding that the cucumbers will soften slightly over time.
