Since i moved to new york city over 2 years ago and discovered the amazing food truck offer, ive made it my job to try as many food trucks as i can. From the ones ive tried so far, my favorites are the ones where the simple grilled cheese sandwich is transformed into sophisticated creations with everything from champagne vinegar pickled onions and caramelized granny smith apples, to sauted collard greens and corn chili butter. My many visits to these grilled cheese sandwich restaurants on wheels have also awakened a new passion of mine: creating my own grilled cheese sandwich. The more i experiment, the more amazing combinations i find, and the one im sharing here today is one of my definite winners: queso fresco and gouda, caramelized onions, jalapeo peppers and mustard. The perfect dinner, if you ask me.
