Fill a large pot with water, add 1/2 tbsp of salt and bring to a boil. Add the broccoli and boil for 5 minutes. Then transfer to a bowl of ice water (to stop the cooking process) and drain.
Place all of the ingredients apart from the breadcrumbs and flour into a food processor and pulse for around 3 minutes. Add the breadcrumbs and flour and stir until combined.
Divide the mixture into four even portions and form each portion into a patty. Place on a baking sheet and place in the fridge for 10 minutes to firm up.
Preheat a large frying pan with vegetable oil. Add broccoli patties to the pan and cook for around 4 minutes each side on medium heat.
