Cut the chilli into pieces and place into the Zyliss EasyPull Food Processor with the coriander. Pull 6-8 times to give a fine chop.
Add the pineapple and pull again to cut the fruit into small pieces. Transfer to a bowl.
Quarter the onion, and finely chop in the EasyPull. Add to the bowl with the coriander and chilli, then season to taste with lime juice and salt.
If you don't have an EasyPull Food Processor, chop everything finely by hand.
To make the burgers, place the ingredients into a bowl and combine everything together well. Divide into 4 portions and make into burger shapes, or use a burger press if you have one.
Grill the burgers (under a grill or on the BBQ) for 5 minutes or so one each side until cooked through.
Place the cooked jerk burgers onto hamburger buns with shredded lettuce and a spoonful of the relish.
Serve with plantain chips.
