Gather the ingredients.
In a large mixing bowl, place the meat, ginger and garlic pastes, chopped coriander, chopped green chilies, soaked breadcrumbs, spice powders, salt, and lime or lemon juice. Mix thoroughly to blend all ingredients.
Line a plate with parchmentpaper. Divide meat mixture into 4 portions and form into patties. Place the patties on a lined plate and set aside.
Heat about 1/2-inch ofoil in a large griddle or frying pan over low to medium heat. When hot, add the patties (do not overcrowd the pan) and cook on both sides until done to your likeness, 3 to 5 minutes a side.
While the patties are cooking, slice each bun, open and lightly toast on a grill or in a toaster oven. Butter as desired and spread about 1 tablespoonof mint-coriander chutney on each bun.
Place a cooked patty on each bun and add onion and tomato. Season with salt if desired, close the bun and serve right away.
