Drain the jackfruit and put it into a food processor. Add the garlic, sundried tomatoes, dill, spring onions and tomato purée. Season with salt and pepper.
Whiz for a few seconds, then add the peas, dill and lemon zest. Whiz again, until you get a coarse mixture.
Spoon the mixture into a mixing bowl and add enough oatmeal to have a malleable mixture. Set aside for 10-30 minutes.
Meanwhile, prepare your condiments, salads, toppings and buns for the burgers.
When you’re ready to cook the patties, form about 6 or 8 equal sized balls from the mixture, then flatten these between your palms.
Put the patties onto a lined baking sheet and bake in a hot oven for 15 to 20 minutes until golden, or fry them in a pan over medium heat for five minutes or so, until golden.
Assemble the burgers with your chosen buns,toppings and condiments.
