As an urban dweller, I must confess that grilling season leaves me frustrated. I love grilled food, everything from veg to haloumi cheese to meat and even fruit. A touch of char and smoke is all it takes for me to start salivating. In my current situation, however, I have no backyard, porch, balcony, rooftop or fire escape in which to perch even the smallest of grills. It got me to thinking about how others approach their summer grilling plans. A nice suburban yard offers numerous possibilities, but what about apartment building dwellers?
