In a small mixing bowl, combine the salt, pepper, garlic powder, and onion powder to create your seasoning mix.

Divide the meat into eight equal portions, each weighing approximately 3 ounces, and shape them into balls.
03 -
Preheat your flat-top grill and lightly coat it with vegetable oil to prevent sticking.
04 -
Lightly sprinkle the seasoning mix over the top of each meatball.

Place the meatballs on the grill, seasoned side facing down. Cover each meatball with a piece of parchment paper and use a heavy weight to press them into thin patties, paying extra attention to flatten the edges thoroughly.
06 -
Once flattened, season the exposed side of each patty.
07 -
Allow the patties to cook until the edges brown and the meat looks lacey and crispy, about 2 minutes.
08 -
Carefully slide a scraper under each patty and flip it over. Place a slice of cheese on top of each patty immediately after flipping. Continue cooking until the cheese is thoroughly melted, about 2 minutes.

For double-stack burgers, place one patty on top of another with the cheese in between. Remove the patties from the grill and serve immediately.
