Combine all of the ingredients together and form into six meatballs, flatten out slightly to make burgers.
Fry over a medium heat in a little oil, for 6 minutes on each side until golden brown and thoroughly cooked. Set aside to rest and keep warm.
Meanwhile mix the yogurt and mint sauce together.
To serve, lay some rocket leaves on top of each half toasted roll, set a warm burger on top, and add a spoonful of tomato chutney and a little yogurt and mint sauce.
