FAQs
Can I use frozen green beans for this salad?
Fresh green beans are best for the crisp texture, but if using frozen, thaw them fully and pat dry before blanching briefly to avoid sogginess.
How can I make this salad ahead of time?
Prepare and refrigerate the dressing separately. Blanch the beans and cool them, then store all components separately to keep everything fresh. Combine just before serving.
