Grilled Onions with Balsamic Vinegar and Brown Sugar

Grilled onions are the sweet cousin of the bad boy, make you cry raw onions.  Grilled onions still have an edge (as your breath will attest to), but grilled onions are sugary enough to make their way into a cupcake.  Sometimes, however, sweet things can be made even more appealing.

See what I mean?  Well, for grilled onions, balsamic vinegar and brown sugar do the trick.

    These onions would go awesome in a french onion soup – just add beef stock and thyme and voila! :)

    Instead of sugar, I made an awesome balsamic reduction with organic Balsamic vinegar, lemon juice and smashed garlic. After reducing the liquid over med-high to half of it’s consistency, it not only thickens but is hearty AND sweet!! Added to onions after grilling.
