Cut the chicken breast into bite-sized pieces suitable for skewering.
Prepare the tandoori marinade by blending ginger, garlic, salt, ground cumin, Kashmiri chili powder, garam masala, turmeric, fresh coriander, lemon juice, cooking oil, and yoghurt into a smooth mixture.
Place the chicken pieces into the marinade and coat thoroughly.
Cover and refrigerate for at least 4 hours to allow flavors to develop.
Preheat your grill or oven to medium-high heat (about 200°C / 400°F).
Thread the marinated chicken pieces onto skewers.
Place the skewers on the grill or in the oven and cook for about 15 minutes, turning occasionally, until the chicken is cooked through and slightly charred.
Remove from heat and garnish with freshly chopped coriander before serving.
