Instructions
If meat is frozen, allow it to thaw enough to pull it out of the package. Then place the meat in a paper towel-lined bowl and allow to thaw overnight. Letting the liquid drain out of the meat will help the burgers stick together.
Once meat is thawed, add in worcestershire sauce, garlic powder, onion granules, salt, and pepper. Mix together by hand until well-combined.
Divide meat into 4 equal parts. Then divide each quarter into 3 equal parts and roll into balls. You should have 12 balls total.
Cut a piece of parchment paper into a rectangle the size of your griddle. Don't cut it too big or it could catch on fire!
Heat cast iron griddle over high heat. Add lard to pan and spread it around so the whole griddle is coated.
Place meatballs on griddle spaced evenly. They'll need space to be smashed into burgers.
Place parchment paper over meatballs and press down with a sheet pan. Apply pressure all of the sheet pan to make sure you press them all evenly. Don't be afraid to really squish them!
Cook for 2-3 minutes, then flip. As soon as you flip them, top with cheese. Cook an additional 2-3 minutes and remove from griddle.
Spread mayo on each bun half. Place cheeseburgers on bottom halves of buns. Top with ketchup, onions, lettuce, and tomatoes. Enjoy!
