This vegetable has earned a reputation for being elitist, probably because it's rather expensive when bought out of season. But if you're like many people, you may swear it's worth its weight in gold. Gourmet or not, you can't beat the nutrition you get for what asparagus "costs" calorie-wise. At less than four calories a spear, you can't go wrong unless you unwisely top it with Hollandaise sauce.
Asparagus not only has few calories, it also has major flavor. Most people like to savor their spears, a practice that extends the dining experience and so may prevent you from overindulging in other foods.
