Take the chicken in a bowl. Add the ginger garlic paste, turmeric powder, crushed coriander seeds, red chili powder, and cumin powder. Mix them properly.
Next, add the sliced onions and give it a good mix.
Take an aluminum foil sheet. Transfer the chicken mixture to the aluminum foil.
Top it with green chilies, tomatoes, and coriander leaves.
Season with salt and pepper.
Next, fold the aluminum foil and pack the chicken using a thin thread.
Transfer the packed aluminum foil chicken into a steamer and steam for 20-25 minutes. Keep flipping the pack for proper cooking.
Once the chicken is cooked, serve hot with rice or chapati of your choice.
