Think of Whole Foods grocery store as a city unto itself, where the salad bar functions as the "downtown." It's where the natives hunt and gather for the quick pick-up of ready-made meals. Get there early, however, for the healthiest option on the to-go table, the popular raw kale and avocado (with purple onion) salad. It contains no meat, no salad dressing —nothing cooked. How do you make a salad without dressing taste good? By smothering the chopped kale and crisp onion with creamy, squished-up fresh avocado. It's pitched to people on the stringent "raw food" diet, but for anyone's menu, it's a light, refreshing, healthy bowl o' green.
