Preheat a gas grill to medium-high.
Peel and slice the onion into 1/8-inch-thick slices. In a bowl, mix the Wine and Worcestershire Sauce. Add the Brown Sugar and whisk until it is mostly dissolved. Add the onion slices to the bowl, making sure that they are completely coated by the marinade. Set aside.

Flip the remaining baguette slices and add an equal amount (1/4 cup) of the Gruyere to the toasted and buttered side of each slice. Close the grill and let cheese melt for 2-3 minutes.

Garnish each burger with a sprinkle of the remaining parsley. Let cheese topping cool for 1 minute and serve the burgers.
