Meanwhile, prepare the burgers. Start by roasting the almond flakes into a dry frying pan at medium-high heat until golden brown (you don’t need to use any oil or butter).
Heat 1/3 of the olive oil in a non-stick skillet on medium heat. Add chopped shallot and fry lightly. When shallot is shiny, turn off the heat and add the chopped parsley. Mix well.
Add almond flakes, shallot, parsley and mustard to the minced beef and mix well. Season, according to your own taste, with pepper and salt.
Divide the beef into two parts and form burgers. Coat burgers with the flour. Heat the remaining olive oil at medium-high heat and cook the burgers until brown on each side.
