In my recent chronicle (of grilled cheeses), I made public a discussion between a friend and myself on the nature of these so-called grilled cheese sandwiches. This friend noted the opulence of using caramelized onions in a grilled cheese sandwich, and we will not debate his profound wisdom at these proceedings.
Rather, I will say that another sumptuous addition to a grilled cheese is canned, fried onions (please keep in mind this does not mean that caramelized onions are not equally - if not more - delicious).
Fried onion pieces, those tasty little morsels, add a crunchy, savory element of pure deliciousness. Applying the onions liberally to a grilled cheese made with Artisan Reserve Vermont Cheddar, procured from Trader Joe's, you'll find yourself in a truly delightful situation: a situation in which you are munching on pungent, sharp, gooey cheddar and crunchy, wholesome fried onions. A fine situation, to be sure.
Carry on.
