The perfect hamburger

Preheat the oven to 180 degrees Celsius.
Put the diced vegetables in a
baking tray and mix with 40 ml
of the oil. Roast for 30 minutes,
stirring continuously. Remove
from the baking tray and leave
to cool. Remove the skin of the
garlic and mash the flesh. Chop
the steak finely or cut it into 2,5
cm cubes and pulse it 10 times
(no more) in a food processor.
Mix the meat, vegetables and remaining
ingredients well. Divide
the meat mixture into 6 equal
balls and flatten them to make
burger patties. Brush on both
sides with the remaining olive
oil. Heat a cast-iron pan over
high heat and seal the burgers
on both sides. Reduce the heat
and fry for another 4-6 minutes
on each side. The hamburgers
can also be braaied over hot
coals. Add a topping and serve
with a sauce of your choice in
bread rolls or ciabatta.
