This recipe is very close to classic chapli kababs, which are kababs native to the northern parts of Pakistan. Every region has their version, but it's differentiating feature is a slice of tomato pressed into one side. It's then pan fried until it has a nice, crispy crust. This is no way an authentic recipe, but it gives you the best of both worlds, a chapli kabab and a burger...You can skip the burger buns and make these a great gluten free meal.
