This hearty chopped salad is inspired by the Georgian dish ispanakhis pkhali, which is made with spinach. It sometimes is so finely chopped that it is almost a dip or condiment, but we prefer the versions that maintain the different textures and crunch of the ingredients. Instead of spinach, we opted for heartier kale. Along with garlic, oil and vinegar, the greens and walnuts often are dressed with blue fenugreek, which usually requires a trip to a specialty market. While it cannot be copied, we find that a combination of coriander, mustard and fennel approximate its unique flavor.
