Chef Darryl King, owner of Riteway Catering in Phoenix, makes sure no one walks away from his food truck unhappy — or hungry — and he does it with solid, served-fast po'boys priced to please. You'll want the Blazing Pig, made with pulled pork, half a hot link sausage, and slaw packed into a soft but sturdy roll slathered with a spicy sauce. At eight bucks, it's a steal. And with no-charge sides like garlicky tater tots or green chile mac and cheese and addictive "Koolickles" (slices of dill pickles soaked in Kool-Aid), King's food truck reigns supreme.
