|800 g||ground beef|
|4 slices||cheddar cheese|
|4 leaves||iceberg lettuce|
|olilve oil for frying|
|butter for serving|
Preheat the grill. Slice onion into thin rings. Gently sauté half of the onions in some olive oil. Season with salt and pepper.
Season ground beef with some pepper to taste and form into burger patties with damp hands. Create a small well in the middle to prevent the burger from puffing up during cooking.
Place patties on the hot grill and cook for approx. 4 – 5 min. per side, depending on the thickness. Place a slice of cheddar cheese on each patty and let it melt for a minute.
Cut tomato and cucumber into slices. Cut the burger buns lengthwise and butter if desired.
Assemble burger with grilled patties, tomato and cucumber slices, raw onion slices, sautéed onions, iceberg lettuce, ketchup, and mayonnaise. Enjoy!
