Use your hands (or a fork) to mash all of the ingredients together. Once the vegetables and cheese have been fully mixed with the beef, portion the mixture into 6 equal balls (a scale is very helpful to ensure even portions).

Pat the balls into patties ⅓ – ½ inch thick. Arrange in a single layer on a lined sheet pan or stack the patties with a sheet or waxed or parchment paper between each to keep them from sticking together. It is helpful to chill the patties for at least 20 minutes before cooking.

Cook the chilled patties over medium high heat on the stove top or on a grill. Patties need about 3-4 minutes per side to be well done.
