Clean the chicken drumsticks and make cuts on them. Make a paste of garlic, red chili powder, pickle, oil and salt with little water.
Smear this paste all over the chicken drumsticks and marinate for 5-6 hours or preferably overnight in the refrigerator.
Line a baking tray with foil and arrange the marinated chicken legs over it. Grill for 30-35 minutes by basting with oil / leftover marinade and flipping them halfway through.
Garnish with coriander leaves and serve them hot with green chutney.
