Add the ginger-garlic paste and green chilies, and cook until aromatic.
Add the minced meat and cook until it turns brown and any liquid evaporates.
Stir in the cumin powder, coriander powder, turmeric powder, red chili powder, and salt to taste. Mix well.
Cook the mixture for a few more minutes until the spices are well incorporated and the filling is dry.
Garnish with chopped cilantro leaves and set aside to cool.
