Mix the pesto, grated tomato, salt and pepper into the mince with clean hands.

Wet your hands and split the mixture into 10-12 small pieces and then shape each into a patty.

Rub patty with a little olive oil, place in a hot pan and cook for about 2-3 minutes on each side.

While cooking the patties, halve and toast the burger buns in a non-stick frying pan.

Assemble your burger with lettuce, onion, cucumber and tomato as desired.
