Add the garlic, ginger, salt, cilantro, chiles, lemon juice, and oil to a food processor or mortar and pestle and blitz to make an aromatic paste. Set aside.
In a large bowl, add the ground beef, diced onion, egg, bread crumbs, garam masala. Add the cilantro paste and mix using your hands or a rubber spatula until well combined and homogeneous, but no need to work it further.
To form the kebabas, divide the mince into 8 equal portions, about 3 tbsp of minced beef for each kebab. Roll each portion into the shape of a sausage, about 3 inches long and 1/2 inch wide.
In a large frying pan with a lid over a high heat, then reduce the heat to medium low and shallow-fry in batches, partially covered for 10 minutes, or until all the moisture dries up and the kebabs are cooked through. Turn the kebabs frequently until all sides are browned and cooked.
Warm paranthas in a hot skillet for 30 seconds on each side.
To assembly, put 1 kebab in the middle of each paratha, then pour over chutney and tamarind sauce. Top with onion slices and tomato then roll up and enjoy. Serve 2 kebab rolls per person for a meal or one for a snack.
