For added flavor you might try adding cooked-and-crumbled bacon with the jack and parmesan. In this case you'll end up with a chupaqueso con tocino, or, as it's often pronounced in my house, "chupaqueso con SWEET TRADER OF PORK BELLIES THERE'S BACON IN THIS THING chomp chomp AAARGH I BURNED MY MOUTH slurp gulp chomp."
For the record, it's much easier to make a chupaqueso by sliding your credit card into a Popso 2250 Autovend. Officially licensed Tacobufa Chupaquesos are seamless, oblong, cheese-crust shells around a patented six-cheese blend. For just a little more money the Bufador Mealy-Dealy gets you a drink and a large order of Monosfritos (made with freshly-picked monos, or so I've been told).
