Salad seems to be a "go-to" item for people attempting to eat clean and healthy. The problem with salads is that you typically can't prepare them in advance due to wilting and the unfortunate sogginess that occurs when you add other items to wet lettuce. Fortunately, there is a salad that doesn't just withstand the preparation process but actually enhances in flavor and texture as it sits, for days... This massaged kale salad is very simple and nutrient dense.
