Ingredients400 g minced beef
100 g Grana Padano
1 tbsp mild mustard
2 red onions
4 soft sesame seed buns
2 tsp Pickled capers
Extra virgin olive oil
PreparationIn a mixing bowl, combine the minced beef and 50 g of grated Grana Padano, the mustard, capers, chopped parsley, season with salt and pepper, and mix well.
With the help of a round pastry cutter, make 4 burgers and put them aside.
Slice the onions into rings and cook them in a non-stick pan with a drizzle of olive oil, the sugar, salt and pepper, and a small ladleful of warm water. Cover the pan with a lid and cook the onions until soft and caramelised.
Put the onions aside and use the same pan with a drizzle of olive oil to cook the burgers for 6-7 minutes on each side, season with salt and pepper to taste.
On each halved bun, put a few leaves of lettuce, a slice of tomato, a burger (still warm), caramelised onions, shavings of Grana Padano and serve immediately.
