You will need (for two):
250g beef mince
1 medium onion
A splash of Worcestershire sauce
2 small carrots
1 small kohlrabi
Salt and pepper
Burger accessories like cheese, lettuce, buns etc.
Start by making the burgers. Finely chop the onion and add about a third of it to a bowl with the mince, Worcestershire sauce and some salt and pepper. Squeeze all of this together with your hands until well mixed and then form into burger shapes. Fry the burgers in a little oil until cooked.
While the burgers are cooking put the rest of the onion into another bowl and peel and chop the carrots and kohlrabi to the same size as the onion. Stir all of the vegetables together in the bowl with a good dollop of mayonnaise and a little salt and pepper.
When the burgers are almost ready I like to add a thick slice of cheese while they’re still in the pan so it starts to melt. Assemble your burger how you see fit; I would always opt for plentiful gherkins.
