Rinse and drain the chickpeas. Deseed (and perhaps devein) then finely chop the chilli. Roughly grate the carrot and finely chop the coriander.
Mix the chickpeas with the carrot, spices, chilli, egg and coriander in a mixing bowl. Put half of the mixture into a food processor and blend until you get a thick paste.
Transfer the paste back into the mixing bowl. Add the minced lamb, salt & pepper, then combine well.
Make 8-10 balls of the mixture, then slightly flatten them between your palms. Put these patties on a plate and chill for 15-30 minutes, or until you’re ready to cook them.
Heat the grill, griddle or BBQ. Brush the patties lightly with some oil and cook for 4-5 minutes on each side. Alternatively, bake them in a preheated oven for 15-20 minutes, until golden.
Serve the burgers warm with your chosen condiments, side dishes and buns.
