This is another great idea from Sandra, who saw this burger featured on a TV show and promptly made her own version:
1 - 1 1/2 lb ground beef (no leaner than 80%)
4 slices American cheese (NOT cheddar, it has to be American or you won't have the melty delicious gooey mess - note: I've used Swiss, too, which was really good!)
4 gluten free buns
Your favorite condiments and toppings
In a big bowl, combine the beef, salt, garlic, black pepper and onion flakes. (NOTE: instead of the seasonings listed I used 2/3 package of Lipton Onion Soup mix with the ground beef.) Divide into equal 8 portions. Shape each portion into a thin hamburger patty.
Take each slice of cheese and cut into four pieces, stack all four slices in the middle of each of four of the patties. Top with another thin patty and crimp the edges tightly to seal. Cook 3 to 4 minutes on the first side. You'll notice that burger will puff up, that's fine.
Turn the burger over and then gently poke the top with a toothpick or wooden skewer, so the steam can escape.
Cook another 3 to 4 minutes. Serve on a gluten free bun with your favorite condiments.
