Smash burgers

Method

1. 1

   Roll the meat into 8 balls (2 per burger). Heat a grill or pan, add oil, and place the meatballs. If your pan is small, cook in batches. Smash the meat down with a spatula or press, season with salt and pepper, and cook on medium heat until browned. Flip, add cheese near the end, and cover to melt.

2. 2

   For the onions, heat oil in a pan, add sliced onions, and cook on low heat, stirring occasionally. Add a splash of water if they stick, season with salt, and cook until golden brown.

3. 3

   For the sauce, mix mustard, ketchup, mayo, gherkin juice, and chopped gherkins; season with salt and pepper. Toast the burger buns briefly, then assemble the burgers with sauce, onions, and any other veggies you like.
