Lightly mix the ground beef, sauce, and dehydrated onion.
Form the mixture into four balls, 4 ounces each. Use a patty maker to make the 4 patties.
From this point, you can put them on a flexible cutting board, flash freeze, and package them.
To use them right away, heat the grill to very hot. Oil the grill and put the patties on the grill. Let them cook for about a minute, then to make the nice grill marks, do a half turn. Let the burgers cook for another two minutes, then flip, wait one minute and do another half turn.
Top the burgers with the sliced cheese, cover, and cook for an additional minute. Use an instant-read thermometer to make sure they are done to your liking. If you use ground beef from the supermarket, make sure to cook them well done, 160°F / 71.11°C. If you ground the meat yourself (recommended), you can cook them to your liking.
In the meantime, prepare a serving place with the buns. Lightly spread the mayonnaise on each side of the buns and put the lettuce, tomato, and red onion on the side that will be the bun topper.
When the burgers are done, put them on the flat side of the burger bun.
Enjoy!
