- Preheat a grill or grill pan.
- Place the mince in a bowl and season generously with salt and pepper.
- Mix well with your hands. Take a small amount of the ground beef (about two tablespoons) and form it into a meatball in your hand. Flatten the ball slightly and then place the mini burger patties on a plate.
- Drizzle the meatballs with oil on both sides and season with salt and pepper.
- Grill the burgers on a hot grill, first on one side for three minutes, then flip with tongs. Then place a slice of cheddar on top of the burger and let it melt.
- While the cheese is melting, place the burger buns on the grill and lightly toast on both sides for about 2 minutes in total.
- Assemble the burger: Place the toasted brioche halves on a plate. Place a small spoonful of remoulade sauce (see recipe below) on the bottom half. Place the burger patty on top (cheese facing up), place an arugula leaf, a slice of tomato and a slice of cornichon on top. Finally put the other half of the burger bun on top.
