Preheat oven to 450 degrees. Finely chop onion and parsley. Combine beef, onion, parsley, garlic and salt and mix well. Press beef mixture evenly over bottom of a Large Bar Pan. Bake 10-12 minutes or until beef is no longer pink.
Meanwhile, cut cheese into quarters and set aside. Slice Buns into thirds (you can square off the ends to be fancy).
Remove Bar pan from oven and pour off the grease. Cut into 24 squares. Place burgers on buns and top with cheese. You can place back on pan and cover with foil to melt cheese and warm buns. 3-5 mintues.
Top with pickles and any other condiments desired.
