Break apart ground beef with two knives. Blend in the egg, bread crumbs and worcestershire sauce, and mix well.  

Mix together garlic powder, onion powder and salt, and add this to the meat mixture and blend well.

Cover a large cookie sheet with wax paper. Make 6 to 8 meatballs with the mixture. Form each into a round patty and place each on cookie sheet.

Pop cookie sheet into the freezer for 1-2 hours, until the patties are stiff.
