The inspiration for this salad comes from the Seder plate: Although the "bitter herb" is often horseradish, in the Sephardic (or Mediterranean) Jewish world, it can be an assertive green, one with bite. We chose dandelion greens, which are at their peak this time of year. (Please note: for Ashkenazi Jews, the mustard in this recipe is not considered kosher for Passover.)
