Black Bean and Corn Romaine "Tacos"

I love tacos.  My family eats them every Tuesday.  We call it Taco Tuesday!  Sometimes, I like to mix it up and switch my traditional corn tortilla shell for some romaine leaves.  It reduces the caloric value of the meal dramatically (leaving more room for chips and salsa!), and also adds more greens into the meal.  The leaves are easy to use, and you don't miss the crunch effect of a tortilla shell with the crispness of this lettuce leaf.
