Mind-blowing grilled cheese sandwiches

<b>Zillion Dollar Grilled Cheese</b> For the month of April, Deca Restaurant + Bar inside the Ritz-Carlton Chicago is serving up $100 version of the comfort-food classic.  The Zillion Dollar Grilled Cheese features Spanish black Iberico ham  -- famous for its distinctive flavor due to the acorns the pigs eat --artisan sourdough bread, 40-year aged Wisconsin cheddar with 24k gold flakes, white truffle aioli, 100-year-old aged balsamic vinegar, heirloom tomatoes and foie gras. If that's not enough, it's  topped with a sunny-side-up duck egg and served with a skillet of lobster mac.  (Ritz-Carlton Chicago )

<b>PB&amp;J Grilled Cheese</b> What's better than combining the two great comfort-food classics: PB&amp;J and grilled cheese?

The sandwich is made up of Pear, Brie &amp; blueberry Jam.  (South Water Kitchen)

<b>Heavenly and Healthy</b> Going healthy doesn’t mean scrimping on taste.  <a target="_blank" href="http://www.healthymomskitchen.com/healthier-grilled-cheese-sprouts-recipe">HealthyMomKitchen</a> says start with homemade multigrain bread and lots of veggies like sprouts, avocado, tomatoes and pesto. Add Monterey jack, cheddar and Colby cheese.  All good, right?  The healthy part comes in by broiling, not frying the sandwich. (HealthyMomKitchen)

<b>Bread Alert</b> This gorgeous sandwich uses mozzarella and provolone cheeses.  But key to this one, which was posted on <a target="_blank" href="http://keepyourdietreal.com/food/sandwiches/the-best-grilled-cheese-ever/">KeepYourDietReal</a>, is the bread.  Try a flavorful bread like garlic focaccia, but any fresh bread would work well.
