Get all of the ingredients ready: Pre-heat the grill on medium to high heat setting, slice the onions into ½ to ¾ inch thick slices, form the ground beef into 4 – 4 ounce patties, rinse and dry the arugula, measure the cheese, and make the sauce.

Step 1. Reduce the heat on the grill to medium. Season the burgers with salt and pepper, brush the balsamic vinegar and olive oil over the onions. Place the burgers and onions on the grill. Cook the burgers and onions for about 5 to 6 minutes and flip them over, cook for five minutes longer or until the burgers reach your desired doneness.
