Nacho Burger

This burger is from Bobby Flay.  I have never gotten a bad recipe of his, but this one wasn't perfect.  I thought the cheese sauce, while tasty, was odd because it wasn't smooth.  The burger seemed just ok at first, but the longer we ate it, the more we liked it.  I guess it was the unexpected juxtaposition of burger and nacho flavors and textures that we had to become accustom to before we could properly enjoy it.  It was also our first meal on our new grill:).  We had been without one for a while.  We had always had charcoal, but I am happy we now have a propane one.  While I do agree that charcoal has its benefits, it is totally outweighed by the ease of use for the propane.  Oh and I figure that the meal came in at $4.00 per person
