Prepare the Chicken: Place the chicken breasts between two sheets of plastic wrap and gently pound them to an even thickness. This ensures they cook evenly.
To make the Spice Rub: mix the chili powder, Kashmiri chili powder, garlic powder, ground cumin, salt, black pepper, crushed red pepper flakes, and sugar in a small bowl.
Season the Chicken: Drizzle olive oil over the chicken breasts, then rub the spice mixture evenly onto both sides. Let them sit for about 10 minutes to absorb the flavours.
Cook the Chicken
Grilling: Preheat your grill to medium-high heat. Place the chicken on the grill and cook for 6-7 minutes on each side or until the internal temperature reaches 165°F (74°C).
Pan-Frying: Heat a cast-iron skillet over medium-high heat. Add a bit of oil, then cook the chicken for 6-7 minutes on each side or until cooked through.
To serve: Remove the chicken from the heat and let it rest for a few minutes. To balance the heat, serve with a dollop of plain yoghurt.
